Flutter notes

Sizing Widgets:

  • Expanded
  • Flexible
  • LimitedBox <-> ConstrainedBox
  • FittedBox
  • SizedBox

Note: When creating widgets in column / row, if the size is too big (like when presenting in a modal screen) use the attribute: mainAxisSize.min to contain the widget

Use Spacer when you want to create space using a flex property. Use SizedBox when you want to create space using a specific number of logical pixels.

setInterval and clearInterval are top level functions part of JavaScript

What does that mean?

Basically these functions are defined by the window object. You can either call this function like window.setInterval( ... ) or just setInterval( ... )

setinterval is used to call any function again and again every few milliseconds.

It takes 2 parameters: the function to call periodically and what the duration between the calls is. So for example:

HTTP basics

Basic HTTP

The Client Server Model

The core working of the internet is based on the idea of client / server communication. The client is anything close to the user (a web browser, an app, a terminal with ssh) and a server that can respond to client queries.

Clients can talk to servers via a variety of protocols. The protocols are just a way for the client and server to agree on how to send data back and forth. Its like you and I talking. We can agree that we use English and with a friend of mine I can use Hindi.

Different Client / Server protocols include:

  • HTTP
