Styled_widget

This package requires Dart 2.6.0 or newer which implies a Flutter version supporting this Dart version. As of right now Flutter stable does not support these constraints

Basic Example

final styledWidget = (Widget child) => Styled.widget(child)
    .padding(all: 20)
    .backgroundColor(Colors.blue)
    .constraints(width: 100, height: 100)
    .borderRadius(all: 10)
    .elevation(10)
    .alignment(Alignment.center);

@override
Widget build(BuildContext context) => styledWidget(FlutterLogo());
Dart
Native Flutter equivilent 
Align(
  alignment: Alignment.center,
  child: DecoratedBox(
    decoration: BoxDecoration(
      boxShadow: [
        BoxShadow(
          color: Color(0x55000000),
          offset: Offset(0, 10),
          blurRadius: 10,
        ),
      ],
    ),
    child: ClipRRect(
      borderRadius: BorderRadius.circular(10),
      child: ConstrainedBox(
        constraints: BoxConstraints.tightFor(width: 100, height: 100),
        child: DecoratedBox(
          decoration: BoxDecoration(color: Colors.blue),
          child: Padding(
            padding: EdgeInsets.all(10),
            child: FlutterLogo(),
          ),
        ),
      ),
    ),
  ),
),
