flutter之SingleChildScrollView

SingleChildScrollView

SingleChildScrollView类似于Android中的ScrollView，它只能接收一个子组件，定义如下：

SingleChildScrollView({
  this.scrollDirection = Axis.vertical, //滚动方向，默认是垂直方向
  this.reverse = false, 
  this.padding, 
  bool primary, 
  this.physics, 
  this.controller,
  this.child,
})

示例：

Widget build(BuildContext context) {
    String str = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    return Scrollbar(
        child: SingleChildScrollView(
      padding: const EdgeInsets.all(16.0),
      child: Center(
        child: Column(
          children: str
              .split("")
              .map((c) => Text(
                    c,
                    textScaleFactor: 2.0,
                  ))
              .toList(),
        ),
      ),
    ));
  }
