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"
	// }

@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
