关于showModalBottomSheet高度自适应
需求:
1.showModalBottomSheet根据内容大小高度自适应
2.超出最大高度(例如屏幕的三分之二)可以滑动
3.键盘弹出时自适应
static showBottomPop(BuildContext context) {
return showModalBottomSheet(
context: context,
isScrollControlled: true, //可滚动 解除showModalBottomSheet最大显示屏幕一半的限制
shape: RoundedRectangleBorder(
//圆角
borderRadius: BorderRadius.vertical(top: Radius.circular(30.w)),
),
builder: (BuildContext context) {
return AnimatedPadding(
//showModalBottomSheet 键盘弹出时自适应
padding: MediaQuery.of(context).viewInsets, //边距(必要)
duration: const Duration(milliseconds: 100), //时常 (必要)
child: Container(
// height: 180,
constraints: BoxConstraints(
minHeight: 90.w, //设置最小高度(必要)
maxHeight: MediaQuery.of(context).size.height / 1.5, //设置最大高度(必要)
),
padding: EdgeInsets.only(top: 34.w, bottom: 48.w),
decoration: BoxDecoration(borderRadius: BorderRadius.vertical(top: Radius.circular(30.w)), color: Colors.white), //圆角
child: ListView(
shrinkWrap: true, //防止状态溢出 自适应大小
children: <Widget>[
Column(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
//widget组件
],
)
],
),
),
);
});
}
