CodePudding user response：

AlertDialog provides scroll option, You can use scrollable: true,

showDialog(
  context: context,
  builder: (BuildContext context) => AlertDialog(
    scrollable: true,
    content: Column(
      children: List.generate(223, (int index) {
        return ListTile(title: Text("$index"));
      }),
    ),
  ),
);

CodePudding user response：

Try using Expanded() widget which will allow you to give available space and try also giving shrinkWrap: true in ListView()

CodePudding user response：

Please Wrap List.generate With Flexible Widget.
