The problem I have is that I want to run a function before the buildcontext is rendered. What the function does is read the storage to get the token. The function works with Async Await. Why do I want to do this? Because in the build context I have a FutureBuilder and in this I need token data.

class ProfileScreen extends StatefulWidget {
  ProfileScreen({Key? key}) : super(key: key);
  

  @override
  State<ProfileScreen> createState() => _ProfileScreenState();
}

class _ProfileScreenState extends State<ProfileScreen> {
  dynamic token;
  getToken()async{
    token= await decodeJwt();
    print("first this");
    print(token);
    return token;
  }


  @override
  void initState() {
    getToken();
    super.initState();
    
  }


  @override
  Widget build(BuildContext context) {
    print("after this");
    final profileService=Provider.of<ProfileService>(context);
    final listDropDownService=Provider.of<ListDropDown>(context);
    
    return FutureBuilder(
      future: Future.wait([profileService.getSpecificWalker(token["id"]), listDropDownService.getDropDown("services")]),
      builder: (context,dynamic snapshot){

as you can see i used some print also to see what the sequence was like. But first it prints "then this" and then "first this"

What you said shows that you need state manager, because in one state you want to get token then when token get available, call the futureBuilder. I recommended bloC.

CodePudding user response：

My strongest suggestion would be to use some state management solution, such as flutter_bloc, that is not directly dependent on the UI components.

If not, then why don't you just try and wrap the getToken() method and the profileService.getSpecificWalker(token["id"]) call in a single async method and call that from the FutureBuilder.
