Writing repetitive code can feel really boring and unproductive. VS Code provide us with a way to write reusable code: Enter 鈥淪nippets.鈥 A VS Code Snippet is just a piece of reusable code that can be generated with a short word.

"Widget with ListView.builder": {
		"prefix": "rwstlesslvb",
		"body": [

		],
		"description": "Creates a Statelss widget with ListView.builder"
	}
class  extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      itemBuilder: (BuildContext context, int index){

      },
    );
  }
}
...
"body": [
  "class  extends StatelessWidget {",
  "\t@override",
  "\tWidget build(BuildContext context) {",
  "\t\treturn ListView.builder(",
  "\t\t\titemBuilder: (BuildContext context, int index){",
  "\t\t\t\t",
  "\t\t\t},",
  "\t\t);",
  "\t}",
  "}",
],

...
"body": [
  "class $1 extends StatelessWidget {",
  "\t@override",
  "\tWidget build(BuildContext context) {",
  "\t\treturn ListView.builder(",
  "\t\t\titemBuilder: (BuildContext context, int index){",
  "\t\t\t\treturn $2",
  "\t\t\t},",
  "\t\t);",
  "\t}",
  "}",
],
...
