快捷生成Widget

-------------------------------------------------------------------------

Flutter 相关问题记录(持续更新):

  1. 通常系统widget的部分属性都会有默认值,使用时候需要注意

  1. 在约束性布局中使用container()作为空视图会有问题:

原因container为空时会返回:

limitedBox(

maxWidth: 1.0,

maxHeight: 1.0,

child: ConstrainedBox(constraints: BoxConstraints.expand()),

);

而limitbox在父组件有约束的时候不会生效,导致实际会返回  ConstrainedBox(constraints: BoxConstraints.expand()),大小的子项.

  1. CircleAvatar  在没有设置radius时,默认最大只有2x20的大小,所以如果需要设置大于40的size需要手动指定radius大小为实际大小/2

_defaultRadius  = 20.0

double get _maxDiameter {

if (radius == null && minRadius == null && maxRadius == null) {

return _defaultRadius * 2.0;

}

return 2.0 * (radius ?? maxRadius ?? _defaultMaxRadius);

}

  1. AS找不到设备

a.Search everywhere (Shift + Shift)

b.Search for restart flutter daemon

  1. stack:

使用position的时候如果不指定边界位置会导致内部控件的边界无限,导致UI的一些问题:

例如Text的 长度超出屏幕之后不会自动换行或自动裁剪
