Dot shorthands
Write more concise Dart code! We’re excited to announce a new Dart feature — dot shorthands! Shorthands reduces boilerplate by letting you omit types that Dart can infer.

For example, you can use shorthands to write .start instead of MainAxisAlignment.start .

// With shorthands
Column(
mainAxisAlignment: .start,
crossAxisAlignment: .center,
children: [ /* ... */ ],
),

// Without shorthands
Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.center,
children: [ /* … */ ],
),
This also works for named constructors! You can write .all instead of EdgeInsets.all:

Padding(
padding: .all(8.0),
child: Text('Hello world'),
),
This feature is on by default in Dart 3.10 and Flutter 3.38. For more information, check out the dot shorthands page on dart.dev. You can also read about this and more (like Dart hooks!) in the Dart 3.10 release blog post.
