为了实现可自适应宽度的组件,可以使用fractionalFormPercentWidth方法。例如: Padding( padding: const EdgeInsets.all(16), child: Container( width: fractionalFormPercentWidth(context, 0.5), color: Colors.blue, child: Text('宽度为屏幕50%'), ), ), 高级布局与优化:提升用户体验 学习使用Column、Row的交...

Expanded 可以使 Row、Column、Flex 里面的组件填充沿着主轴可利用的空间,如果多个 Widget 都使用了 Expanded 组件,可以使用 Expanded 的 flex 属性按照比例分配主轴空间,flex 属性相当于 Android LinearLayout 的 weight 属性 classHomePageextendsStatelessWidget{constHomePage({super.key});@overrideWidgetbuild(BuildContext...
