I want to display in a SimpleDialog a ListView that I get from my api. But it throws this error

The following assertion was thrown during performLayout(): 'package:flutter/src/rendering/viewport.dart': Failed assertion: line 1895 pos 16: 'constraints.hasBoundedHeight': is not true. The relevant error-causing widget was ListView

my SimpleDialog

showDialog(
  context: context,
   builder: (BuildContext context) {
    return SimpleDialog(
    contentPadding: EdgeInsets.zero,
     children: [
        Column(
         mainAxisSize:MainAxisSize.min,

You need to provide height for horizontal ListView,

 FutureBuilder<List>(
    builder: (BuildContext context, AsyncSnapshot snapshot) {
  return Container(
    height: 100, // the one  you prefer
    child: ListView.builder(

showDialog(
  context: context,
  builder: (BuildContext context) {
    return SimpleDialog(
      contentPadding: EdgeInsets.zero,
      children: [
        Column(
          mainAxisSize: MainAxisSize.min,
          children: [
            Container(
              child: Column(
                children: [
                  const Text('Athletes'),

                    height: 300,
                    width: double.maxFinite,
