Sort child properties last in widget instance creations. This improves readability and plays nicest with UI as Code visualization in IDEs with UI as Code Guides in editors (such as IntelliJ) where Properties in the correct order appear clearly associated with the constructor call and separated from the children.

BAD:

dart
return Scaffold(
  appBar: AppBar(
    title: Text(widget.title),
  ),
  body: Center(
    child: Column(
      children: <Widget>[
        Text(
          'You have pushed the button this many times:',
         ),
        Text(
          '$_counter',
          style: Theme.of(context).textTheme.display1,
         ),
      ],
      mainAxisAlignment: MainAxisAlignment.center,
    ),
    widthFactor: 0.5,
  ),
  floatingActionButton: FloatingActionButton(
    child: Icon(Icons.add),
    onPressed: _incrementCounter,
    tooltip: 'Increment',
  ),
);

GOOD:

dart
return Scaffold(
  appBar: AppBar(
    title: Text(widget.title),
  ),
  body: Center(
    widthFactor: 0.5,
    child: Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: <Widget>[
        Text(
          'You have pushed the button this many times:',
         ),
        Text(
          '$_counter',
          style: Theme.of(context).textTheme.display1,
         ),
      ],
    ),
  ),
  floatingActionButton: FloatingActionButton(
    onPressed: _incrementCounter,
    tooltip: 'Increment',
    child: Icon(Icons.add),
  ),
);

Exception: It's allowed to have parameter with a function expression after the child property.

使用方法

要启用 sort_child_properties_last 规则，请在你的 analysis_options.yaml 文件中，在 linter > rules 下添加 sort_child_properties_last ：

yaml
linter:
