Mis Snippets de Dart

dart.json

{
	// Place your snippets for dart here. Each snippet is defined under a snippet name and has a prefix, body and 
	// description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
	// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the 
	// same ids are connected.
	// Example:
	// "Print to console": {
	// 	"prefix": "log",
	// 	"body": [
	// 		"console.log('$1');",
	// 		"$2"
	// 	],
	// 	"description": "Log output to console"
	// }

Hola, el segundo y tercer snippet hacen exactamente lo mismo, en el primero hay que cambiar la descripción

Hola grupo alguien me puede explicar como poder instalar los snippets es que estoy confundido porque siempre los he instalado en el marketplace de vsc por el nombre pero de esa forma como los instalo?

@StivenOsuna9909 en VSC pulsa la combinación de teclas Ctrl+Shift+p en windows Cmd+Shift+P o el shortcut que tengas configurado para que aparezca la paleta de comandos, en la ventana que aparece escribes 'Snippets' y seleccionas la opción 'Configurar fragmentos de usuario', escribes 'dart.json' y lo seleccionas, se abre una ventana de texto, pegas el código ahí y le das a guardar, eso es todo

Este snippet es con Scaffold!

	"A new Flutter Screen with a Scaffold": {
		"prefix": "fl-screen",
		"body": [
			"import 'package:flutter/material.dart';",
			"",
			"class ${1:Home}Screen extends StatelessWidget {",
			"   ",
			"  const ${1:Home}Screen({Key? key}) : super(key: key);",
			"  ",
			"  @override",
			"  Widget build(BuildContext context) {",
			"    return const Scaffold(",
			"      body: Center(",
			"         child: Text('${1:Home}Screen'),",
			"      ),",
			"    );",
			"  }",
			"}"			
		],
