Flutter: ListView in a SimpleDialog

Question

I want to show a SimpleDialog with ListView.builder in my Flutter app with this code:

showDialog(
  context: context,
  builder: (BuildContext context) {
           


        

Answer 1

SImply in the content we need to use a Container with fixed height and width. and the use ListView as a child of Container.

 scrollDialogFunction(){
        return showDialog(
            context: context,
            builder: (BuildContext context) {
              return AlertDialog(
                title: Text('List of Index'),
                content: Container(
                  width: 350.0,
                  height: 250,// Change as per your requirement
                  child: ListView.builder(
                    itemCount: 150,
                    itemBuilder: (BuildContext context, int index) {
                      return ListTile(
                        title: Text(index.toString()),
                      );
                    },
                  ),
                ),
                actions: [Padding(
                  padding: const EdgeInsets.all(8.0),
                  child: Text("ok",style: TextStyle(fontSize: 18),),
                )],
              );
            });
      }
