I think the scope is only valid if you're adding the snippets globally. If you're adding them to dart.json they're already scoped and you'll get the warning (but they still work).

@manafire and @KDCinfo I've removed it.

Is it possible to use this in Android studio?

# line:36:  " const ${1}({Key key}) : super(key: key);",

# dart error 
# The parameter 'key' can't have a value of 'null' because of its type, but the implicit default value is 'null'.
# Try adding either an explicit non-'null' default value or the 'required' modifier.dart(missing_default_value_for_parameter)

 # Does it need to be changed? -> ({ Key? key })

# line:36:  " const ${1}({Key key}) : super(key: key);",

# dart error 
# The parameter 'key' can't have a value of 'null' because of its type, but the implicit default value is 'null'.
# Try adding either an explicit non-'null' default value or the 'required' modifier.dart(missing_default_value_for_parameter)

 # Does it need to be changed? -> ({ Key? key })

I think so... also if you have linting option dart(prefer_const_constructors) enabled, you need to change ...

#line:42 => const Scaffold()

awesome snippet!

Please, how do I add this snippet in android studio?

How do I get this to work on IntelliJ IDEA? I think they handle snippets differently.

I also had the same Issue. I am just working without it for now, as I am yet to have my way around how to use it in intelliJ.

line:36:  " const ${1}({Key key}) : super(key: key);",

dart error 
The parameter 'key' can't have a value of 'null' because of its type, but the implicit default value is 'null'.
Try adding either an explicit non-'null' default value or the 'required' modifier.dart(missing_default_value_for_parameter)

Does it need to be changed? -> ({ Key? key })

I agree

Updated line:36: " const ${1}({Key key}) : super(key: key);", to ({ Key? key })

How to convert these snippets for use in Android Studio

1. Create a Dart scratch file (Cmd+Shift+N)
2. Paste in the body of any snippet into the scratch file
3. Remove the double quotes and extra commas (Cmd+R is the replace command)
4. Replace the token placeholders with variable names (${1} => $placeholderName$)
5. Highlight the transformed code, and go to Tools > Save as Live Template
6. Add the abbreviation and description as seen in the dialog box below
7. Make sure to add a default value to each variable used (see the edit variables button on live template dialog below)
8. Once saved you can use the stkv template anywhere in the Flutter/Dart scope

For example (transform the body of stkv - line 31 from this)

"import 'package:flutter/material.dart';",
      "import 'package:stacked/stacked.dart';",
      "",
      "class ${1} extends StatelessWidget {",
      " const ${1}({Key? key}) : super(key: key);",
      "",
      " @override",
      " Widget build(BuildContext context) {",
      "   return ViewModelBuilder<${1}Model>.reactive(",
      "     builder: (context, model, child) => Scaffold(),",
      "     viewModelBuilder: () => ${1}Model(),",
      "   );",
      " }",
      "}"

The translated snippet should look something like this:

import 'package:flutter/material.dart';
import 'package:stacked/stacked.dart';

class $classname$ extends StatelessWidget {
 const $classname$({Key? key}) : super(key: key);

 @override
 Widget build(BuildContext context) {
   return ViewModelBuilder<$viewName$Model>.reactive(
     builder: (context, model, child) => Scaffold(),
     viewModelBuilder: () => $viewName$Model(),
   );
 }
}

Live Template Dialog box

P.S.
Pretty sure this will work for IntelliJ as well since AS is built on top
