CodePudding user response：

try this:

return FutureBuilder(future: _getTeamapi(),builder: (context, snapshot){
      if (snapshot.connectionState == ConnectionState.waiting) {
        return Text('Loading....');
      } else {
        if (snapshot.hasError) {
          return Text('has error');
        } else {
          return ListView.builder(itemBuilder: itemBuilder);
        }
      }
    });

CodePudding user response：

Create a future variable on state class to avoid getting unwanted api call.

  late final _future  = _getTeamApi();

Now the future can provide error, empty data list.

Try

FutureBuilder<List<Team>>(
  future:_future ,
  builder: (context, snapshot) {
    if(snapshot.hasError){
      return Text("got error ${snapshot.error}");
    }
    if (snapshot.hasData) {
      if (snapshot.data == null || snapshot.data!.isEmpty) {
        return Text("Could not find any data");
      }
      return ListView.builder(itemBuilder: itemBuilder)
    }
    return CircularProgressIndicator();
  },
),
