Flutter Plus

Extension add some useful commands to Flutter development in Visual Studio Code.

Wrap with...

This package extends your Flutter development experience by providing convenient snippets and commands for wrapping widgets with other commonly used Flutter widgets, similar to the "Wrap with..." functionality in Flutter's built-in extension for VS Code. These additions streamline the process of encapsulating your widgets within other widgets that enhance functionality or control, such as state management, repaint isolation, and more.

Simply select the widget you want to wrap, and choose the appropriate "Wrap with..." command from the command palette, or use the provided snippets to quickly insert the desired wrapper code into your widget tree.

This extension includes the following standard "Wrap with..." commands:

Wrap with ListenableBuilder: Easily wrap any widget with a ListenableBuilder to rebuild the widget based on changes in a Listenable object.
Wrap with ValueListenableBuilder: Automatically wrap your widget with a ValueListenableBuilder to react to changes in a ValueListenable<T>.
Wrap with RepaintBoundary: Encapsulate your widget within a RepaintBoundary to isolate its repaint process, improving performance in complex UIs.
Wrap with SliverPadding: Wrap your widget with a SliverPadding to add padding around a sliver widget in a CustomScrollView.

In order to add custom "Wrap with" commands, you can change the configuration in flutter-plus.wraps settings. The configuration is an array of objects with the following properties:

name: The name of the command that will appear in the command palette.
body: The snippet body that will be inserted into the editor when the command is executed. Use ${0...N} to indicate the position of the selected text. In order to insert the selected text, use ${widget}.

Example configuration:

{
  "wraps": [
    {
      "name": "Wrap with CustomWidget",
      "body": [
        "CustomWidget(",
        "  child: ${widget},",
        ")"
      ]
    }
  ]
}
