更好的方法是使用
列表视图
并使其子项对齐
并设置
对齐
属性

ListView(
  children: <Widget>[
    Align(
      alignment: Alignment.centerLeft,
      child: LeftWidget1(), // widget at left
    ),
    Align(
      alignment: Alignment.center,
      child: CenterWidget1(), // widget at center
    ),
    Align(
      alignment: Alignment.centerRight,
      child: RightWidget1(), // widget at right
    ),
  ],
)
