Flutter＆AlertDialog：如何将其与底部对齐？我该如何制作2个这样的警告对话框？请在此图片中有很多内容。

showDialog(
                                context: context,builder: (BuildContext context) {
                                  double width =
                                      MediaQuery.of(context).size.width;
                                  double height =
                                      MediaQuery.of(context).size.height;
                                  return AlertDialog(
                                    backgroundColor: Colors.transparent,contentPadding: EdgeInsets.zero,title: Center(
                                        child: Text("Evaluation our APP")),content: Container(

                                       // What Should I write here?

                                    )
                                },);

解决方法

这是解决方案之一：

          showDialog(
            context: context,builder: (BuildContext context) {
              double width = MediaQuery.of(context).size.width;
              double height = MediaQuery.of(context).size.height;
              return AlertDialog(
                  backgroundColor: Colors.transparent,contentPadding: EdgeInsets.zero,elevation: 0.0,// title: Center(child: Text("Evaluation our APP")),content: Column(
                    mainAxisAlignment: MainAxisAlignment.end,children: [
                      Container(
                        padding: const EdgeInsets.all(8.0),decoration: BoxDecoration(
                            color: Colors.white,borderRadius:
                                const BorderRadius.all(Radius.circular(10.0))),child: Column(
                          children: [
                            Text("a"),Divider(),Text("b"),Text("c"),],),SizedBox(
                        height: 10,Container(
                        padding: const EdgeInsets.all(8.0),child: Center(child: Text("d")),)
                    ],));
            },);

,

这是我的答案，没有创建 AlertDialog 的纯小部件：

    final content = Column(
      mainAxisAlignment: MainAxisAlignment.end,children: [
        Container(
          decoration: BoxDecoration(
            color: Colors.white,borderRadius: const BorderRadius.all(Radius.circular(10.0)),child: Column(
            crossAxisAlignment: CrossAxisAlignment.stretch,children: [
              TextButton(onPressed: () {},child: Text("a"),Divider(height: 1,TextButton(onPressed: () {},child: Text("b"),child: Text("c"),SizedBox(
          height: 10,Container(
          width: double.infinity,decoration: BoxDecoration(
            color: Colors.white,borderRadius:
            const BorderRadius.all(Radius.circular(10.0)),child: TextButton(onPressed: () {},child: Text("d"),SizedBox(
          height: 40,);

    showDialog(
      context: context,builder: (ctx) {
        return FractionallySizedBox(
          widthFactor: 0.9,child: Material(
            type: MaterialType.transparency,child: content,);
      }
    );

由于文字绘制错误，必须添加Material。
