natebosch/dartlang-snippets

A collection of snippets for writing Dart. Start by reading about UltiSnips if you haven't used if before.

Some of the snippets that save the most typing.

Import line. im<tab>some_package becomes import 'package:some_package/some_package.dart';

For-in loop. for<tab>element becomes

for(var element in elements) {
  |
}

Try-catch. Most useful from visual mode with a block selected, fills the selection in the try, then tab to fill out the catch.

Each of these triggers has 2 modes. At the beginning of the line they generate a top-level/instance method. After other characters they generate a closure.

• m

  • m<tab>ReturnType<tab>methodName<tab>ArgType argument becomes

    ReturnType methodName(ArgType argument) {
      |
    }

  • After other characters: m<tab>argument becomes

    (argument) {
      |
    }

• r

  • r<tab>ReturnType<tab>methodName<tab>ArgType argument becomes

    ReturnType methodName(ArgType argument) => |

  • After other characters: r<tab>argument becomes

    (argument) => |

Prepending either trigger with a makes it use 'async mode'. For example, at the beginning of a line:

ar<tab>ReturnType<tab>methodName<tab>ArgType argument becomes

Future<ReturnType> methodName(ArgType argument) async => |

A @Component annotation and class. Saves the most time if you follow a naming convention: a class name SomeName has a selector like some-name, a template at some_name.html, and styles at some_name.css or some_name.scss.css. Fills out a default name which works well if this component lives in a file named some_name.dart.
