/**
 * Basic composable that enables users to edit text via hardware or software keyboard, but
 * provides no decorations like hint or placeholder.
 *
 * Whenever the user edits the text, [onValueChange] is called with the most up to date state
 * represented by [String] with which developer is expected to update their state.
 *
 * Unlike [TextFieldValue] overload, this composable does not let the developer to control
 * selection, cursor and text composition information. Please check [TextFieldValue] and
 * corresponding [BasicTextField] overload for more information.
 *
 * It is crucial that the value provided in the [onValueChange] is fed back into [BasicTextField] in
 * order to have the final state of the text being displayed.
 *
 * Example usage:
 * @sample androidx.compose.foundation.samples.BasicTextFieldWithStringSample
 *
 * Please keep in mind that [onValueChange] is useful to be informed about the latest state of the
 * text input by users, however it is generally not recommended to modify the value that you get
 * via [onValueChange] callback. Any change to this value may result in a context reset and end
 * up with input session restart. Such a scenario would cause glitches in the UI or text input
 * experience for users.
 *
 * This composable provides basic text editing functionality, however does not include any
 * decorations such as borders, hints/placeholder. A design system based implementation such as
 * Material Design Filled text field is typically what is needed to cover most of the needs. This
 * composable is designed to be used when a custom implementation for different design system is
 * needed.
 *
 * For example, if you need to include a placeholder in your TextField, you can write a composable
 * using the decoration box like this:
 * @sample androidx.compose.foundation.samples.PlaceholderBasicTextFieldSample
 *
 * If you want to add decorations to your text field, such as icon or similar, and increase the
 * hit target area, use the decoration box:
 * @sample androidx.compose.foundation.samples.TextFieldWithIconSample
 *
 * In order to create formatted text field, for example for entering a phone number or a social
 * security number, use a [visualTransformation] parameter. Below is the example of the text field
 * for entering a credit card number:
 * @sample androidx.compose.foundation.samples.CreditCardSample
 *
 * @param value the input [String] text to be shown in the text field
 * @param onValueChange the callback that is triggered when the input service updates the text. An
 * updated text comes as a parameter of the callback
 * @param modifier optional [Modifier] for this text field.
 * @param enabled controls the enabled state of the [BasicTextField]. When `false`, the text
 * field will be neither editable nor focusable, the input of the text field will not be selectable
 * @param readOnly controls the editable state of the [BasicTextField]. When `true`, the text
 * field can not be modified, however, a user can focus it and copy text from it. Read-only text
 * fields are usually used to display pre-filled forms that user can not edit
 * @param textStyle Style configuration that applies at character level such as color, font etc.
 * @param keyboardOptions software keyboard options that contains configuration such as
 * [KeyboardType] and [ImeAction].
 * @param keyboardActions when the input service emits an IME action, the corresponding callback
 * is called. Note that this IME action may be different from what you specified in
 * [KeyboardOptions.imeAction].
 * @param singleLine when set to true, this text field becomes a single horizontally scrolling
 * text field instead of wrapping onto multiple lines. The keyboard will be informed to not show
 * the return key as the [ImeAction]. [maxLines] and [minLines] are ignored as both are
 * automatically set to 1.
 * @param maxLines the maximum height in terms of maximum number of visible lines. It is required
 * that 1 <= [minLines] <= [maxLines]. This parameter is ignored when [singleLine] is true.
 * @param minLines the minimum height in terms of minimum number of visible lines. It is required
 * that 1 <= [minLines] <= [maxLines]. This parameter is ignored when [singleLine] is true.
 * @param visualTransformation The visual transformation filter for changing the visual
 * representation of the input. By default no visual transformation is applied.
 * @param onTextLayout Callback that is executed when a new text layout is calculated. A
 * [TextLayoutResult] object that callback provides contains paragraph information, size of the
 * text, baselines and other details. The callback can be used to add additional decoration or
 * functionality to the text. For example, to draw a cursor or selection around the text.
 * @param interactionSource the [MutableInteractionSource] representing the stream of
 * [Interaction]s for this TextField. You can create and pass in your own remembered
 * [MutableInteractionSource] if you want to observe [Interaction]s and customize the
 * appearance / behavior of this TextField in different [Interaction]s.
 * @param cursorBrush [Brush] to paint cursor with. If [SolidColor] with [Color.Unspecified]
 * provided, there will be no cursor drawn
 * @param decorationBox Composable lambda that allows to add decorations around text field, such
 * as icon, placeholder, helper messages or similar, and automatically increase the hit target area
 * of the text field. To allow you to control the placement of the inner text field relative to your
 * decorations, the text field implementation will pass in a framework-controlled composable
 * parameter "innerTextField" to the decorationBox lambda you provide. You must call
 * innerTextField exactly once.

/**
 * <a href="https://m3.material.io/components/text-fields/overview" class="external" target="_blank">Material Design outlined text field</a>.
 *
 * Text fields allow users to enter text into a UI. They typically appear in forms and dialogs.
 * Outlined text fields have less visual emphasis than filled text fields. When they appear in
 * places like forms, where many text fields are placed together, their reduced emphasis helps
 * simplify the layout.
 *
 * ![Outlined text field image](https://developer.android.com/images/reference/androidx/compose/material3/outlined-text-field.png)
 *
 * See example usage:
 * @sample androidx.compose.material3.samples.SimpleOutlinedTextFieldSample
 *
 * If apart from input text change you also want to observe the cursor location, selection range,
 * or IME composition use the OutlinedTextField overload with the [TextFieldValue] parameter
 * instead.
 *
 * @param value the input text to be shown in the text field
 * @param onValueChange the callback that is triggered when the input service updates the text. An
 * updated text comes as a parameter of the callback
 * @param modifier the [Modifier] to be applied to this text field
 * @param enabled controls the enabled state of this text field. When `false`, this component will
 * not respond to user input, and it will appear visually disabled and disabled to accessibility
 * services.
 * @param readOnly controls the editable state of the text field. When `true`, the text field cannot
 * be modified. However, a user can focus it and copy text from it. Read-only text fields are
 * usually used to display pre-filled forms that a user cannot edit.
 * @param textStyle the style to be applied to the input text. Defaults to [LocalTextStyle].
 * @param label the optional label to be displayed inside the text field container. The default
 * text style for internal [Text] is [Typography.bodySmall] when the text field is in focus and
 * [Typography.bodyLarge] when the text field is not in focus
 * @param placeholder the optional placeholder to be displayed when the text field is in focus and
 * the input text is empty. The default text style for internal [Text] is [Typography.bodyLarge]
 * @param leadingIcon the optional leading icon to be displayed at the beginning of the text field
 * container
 * @param trailingIcon the optional trailing icon to be displayed at the end of the text field
 * container
 * @param prefix the optional prefix to be displayed before the input text in the text field
 * @param suffix the optional suffix to be displayed after the input text in the text field
 * @param supportingText the optional supporting text to be displayed below the text field
 * @param isError indicates if the text field's current value is in error. If set to true, the
 * label, bottom indicator and trailing icon by default will be displayed in error color
 * @param visualTransformation transforms the visual representation of the input [value]
 * For example, you can use
 * [PasswordVisualTransformation][androidx.compose.ui.text.input.PasswordVisualTransformation] to
 * create a password text field. By default, no visual transformation is applied.
 * @param keyboardOptions software keyboard options that contains configuration such as
 * [KeyboardType] and [ImeAction]
 * @param keyboardActions when the input service emits an IME action, the corresponding callback
 * is called. Note that this IME action may be different from what you specified in
 * [KeyboardOptions.imeAction]
 * @param singleLine when `true`, this text field becomes a single horizontally scrolling text field
 * instead of wrapping onto multiple lines. The keyboard will be informed to not show the return key
 * as the [ImeAction]. Note that [maxLines] parameter will be ignored as the maxLines attribute will
 * be automatically set to 1.
 * @param maxLines the maximum height in terms of maximum number of visible lines. It is required
 * that 1 <= [minLines] <= [maxLines]. This parameter is ignored when [singleLine] is true.
 * @param minLines the minimum height in terms of minimum number of visible lines. It is required
 * that 1 <= [minLines] <= [maxLines]. This parameter is ignored when [singleLine] is true.
 * @param interactionSource the [MutableInteractionSource] representing the stream of [Interaction]s
 * for this text field. You can create and pass in your own `remember`ed instance to observe
 * [Interaction]s and customize the appearance / behavior of this text field in different states.
 * @param shape defines the shape of this text field's border
 * @param colors [TextFieldColors] that will be used to resolve the colors used for this text field
 * in different states. See [OutlinedTextFieldDefaults.colors].

/**
 * <a href="https://material.io/components/text-fields#filled-text-field" class="external" target="_blank">Material Design filled text field</a>.
 *
 * Filled text fields have more visual emphasis than outlined text fields, making them stand out
 * when surrounded by other content and components.
 *
 * ![Filled text field image](https://developer.android.com/images/reference/androidx/compose/material/filled-text-field.png)
 *
 * If you are looking for an outlined version, see [OutlinedTextField].
 *
 * A simple single line text field looks like:
 *
 * @sample androidx.compose.material.samples.SimpleTextFieldSample
 *
 * You may provide a placeholder:
 *
 * @sample androidx.compose.material.samples.TextFieldWithPlaceholder
 *
 * You can also provide leading and trailing icons:
 *
 * @sample androidx.compose.material.samples.TextFieldWithIcons
 *
 * To handle the error input state, use [isError] parameter:
 *
 * @sample androidx.compose.material.samples.TextFieldWithErrorState
 *
 * Additionally, you may provide additional message at the bottom:
 *
 * @sample androidx.compose.material.samples.TextFieldWithHelperMessage
 *
 * Password text field example:
 *
 * @sample androidx.compose.material.samples.PasswordTextField
 *
 * Hiding a software keyboard on IME action performed:
 *
 * @sample androidx.compose.material.samples.TextFieldWithHideKeyboardOnImeAction
 *
 * If apart from input text change you also want to observe the cursor location, selection range,
 * or IME composition use the TextField overload with the [TextFieldValue] parameter instead.
 *
 * @param value the input text to be shown in the text field
 * @param onValueChange the callback that is triggered when the input service updates the text. An
 * updated text comes as a parameter of the callback
 * @param modifier a [Modifier] for this text field
 * @param enabled controls the enabled state of the [TextField]. When `false`, the text field will
 * be neither editable nor focusable, the input of the text field will not be selectable,
 * visually text field will appear in the disabled UI state
 * @param readOnly controls the editable state of the [TextField]. When `true`, the text
 * field can not be modified, however, a user can focus it and copy text from it. Read-only text
 * fields are usually used to display pre-filled forms that user can not edit
 * @param textStyle the style to be applied to the input text. The default [textStyle] uses the
 * [LocalTextStyle] defined by the theme
 * @param label the optional label to be displayed inside the text field container. The default
 * text style for internal [Text] is [Typography.caption] when the text field is in focus and
 * [Typography.subtitle1] when the text field is not in focus
 * @param placeholder the optional placeholder to be displayed when the text field is in focus and
 * the input text is empty. The default text style for internal [Text] is [Typography.subtitle1]
 * @param leadingIcon the optional leading icon to be displayed at the beginning of the text field
 * container
 * @param trailingIcon the optional trailing icon to be displayed at the end of the text field
 * container
 * @param isError indicates if the text field's current value is in error. If set to true, the
 * label, bottom indicator and trailing icon by default will be displayed in error color
 * @param visualTransformation transforms the visual representation of the input [value]
 * For example, you can use
 * [PasswordVisualTransformation][androidx.compose.ui.text.input.PasswordVisualTransformation] to
 * create a password text field. By default no visual transformation is applied
 * @param keyboardOptions software keyboard options that contains configuration such as
 * [KeyboardType] and [ImeAction].
 * @param keyboardActions when the input service emits an IME action, the corresponding callback
 * is called. Note that this IME action may be different from what you specified in
 * [KeyboardOptions.imeAction].
 * @param singleLine when set to true, this text field becomes a single horizontally scrolling
 * text field instead of wrapping onto multiple lines. The keyboard will be informed to not show
 * the return key as the [ImeAction]. Note that [maxLines] parameter will be ignored as the
 * maxLines attribute will be automatically set to 1.
 * @param maxLines the maximum height in terms of maximum number of visible lines. It is required
 * that 1 <= [minLines] <= [maxLines]. This parameter is ignored when [singleLine] is true.
 * @param minLines the minimum height in terms of minimum number of visible lines. It is required
 * that 1 <= [minLines] <= [maxLines]. This parameter is ignored when [singleLine] is true.
 * @param interactionSource the [MutableInteractionSource] representing the stream of
 * [Interaction]s for this TextField. You can create and pass in your own remembered
 * [MutableInteractionSource] if you want to observe [Interaction]s and customize the
 * appearance / behavior of this TextField in different [Interaction]s.
 * @param shape the shape of the text field's container
 * @param colors [TextFieldColors] that will be used to resolve color of the text, content
 * (including label, placeholder, leading and trailing icons, indicator line) and background for
 * this text field in different states. See [TextFieldDefaults.textFieldColors]

Its not working

@AhmerAfzal1 It worked last time I used it so you might want to be more specific if you're looking for support.

Outline text field desn't work !!

@vanzar-codigo you might want to be either more specific about the issue you found, or you'll need to post the fix yourself and then the gist will be updated.
