.update not working

[Mychael Go]

Lib version : progress_dialog: ^1.2.0

Sample code:

void _onSavePressed() async {
    try {
      _progressDialog = ProgressDialog(context, isDismissible: false);
      _progressDialog.show();

      if (profilePictureFile != null) {
        _progressDialog.update(
          message: 'Uploading profile picture',
        );
        await _userRepository.uploadProfilePicture(profilePictureFile);
      }

      _user.fullName = _nameController.text;
      _user.phoneNumber = _phoneController.text;
      _user.email = _emailController.text;
      _progressDialog.update(
        message: 'Updating user data',
      );
      await _userRepository.editUserInFirestore(_user);
      print('_onSavePressed ${_user.id}');
      _progressDialog.hide();
    } catch (err) {
      print('err $err');
      _progressDialog.hide();
    }
  }

Output:

err setState() called in constructor: _BodyState#42577(lifecycle state: created, no widget, not mounted)
This happens when you call setState() on a State object for a widget that hasn't been inserted into the widget tree yet. It is not necessary to call setState() in the constructor, since the state is already assumed to be dirty when it is initially created.

Code is working if i comment _progressDialog.update() function

[Mohammad Fayaz]

try writing this line inside the build() method

_progressDialog = ProgressDialog(context, isDismissible: false);

[Mychael Go]

@fayaz07 i've put this code inside build method

_progressDialog = ProgressDialog(context, isDismissible: false);

Error still same

[Mohammad Fayaz]

Can you post sample code, where you have encountered this issue?

[Mychael Go]

Here sample code

import 'dart:async';

import 'package:flutter/material.dart';
import 'package:progress_dialog/progress_dialog.dart';

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

  _TestScreenState createState() => _TestScreenState();
}

class _TestScreenState extends State<TestScreen> {
  ProgressDialog _progressDialog;

  int a = 0;

  void _showLoading() {
    try {
      _progressDialog = ProgressDialog(context, isDismissible: true);
      _progressDialog.show();

      // change variable
      setState(() {
        a=1;
      });

      _progressDialog.update(
        message: 'Uploading profile picture',
      );

      // change variable
      setState(() {
        a=2;
      });

      Timer(
        Duration(seconds: 3),
        () {
          print('must hide now');
          _progressDialog.hide();
        },
      );
    } catch (err) {
      print('err $err');
      _progressDialog.hide();
    }
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      child: RaisedButton(
        onPressed: _showLoading,
        child: Text(
          'Show loading',
        ),
      ),
    );
  }
}

the problem maybe we can't setState if progress dialog is updating

[Mohammad Fayaz]

there is a check, if the progress dialog is showing, only then setState will be called

[Mychael Go]

so what is the solution?

[Mohammad Fayaz]

I haven't checked your code, I will update to you after checking. Thank You

[Mohammad Fayaz]

import 'dart:async';

import 'package:flutter/material.dart';
import 'package:progress_dialog/progress_dialog.dart';

void main(){
  runApp(MaterialApp(home: TestScreen()));
}

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

  _TestScreenState createState() => _TestScreenState();
}

class _TestScreenState extends State<TestScreen> {
  ProgressDialog _progressDialog;

  int a = 0;

  void _showLoading() async{
    try {
      _progressDialog.show();

      await Future.delayed(Duration(seconds: 2));

      // change variable
      setState(() {
        a=1;
      });

      _progressDialog.update(
        message: 'Uploading profile picture',
      );

      // change variable
      setState(() {
        a=2;
      });

//      Timer(
//        Duration(seconds: 3),
//            () {
//          print('must hide now');
//          _progressDialog.hide();
//        },
//      );
      Future.delayed(Duration(seconds: 3)).whenComplete((){
        _progressDialog.hide().then((value){
          print("Hidden: $value");
        });
      });
    } catch (err) {
      print('err $err');
      //_progressDialog.hide();
    }
  }

  @override
  Widget build(BuildContext context) {
    _progressDialog = ProgressDialog(context, isDismissible: true);
    return Scaffold(
      body: Center(
        child: RaisedButton(
            onPressed: _showLoading,
            child: Text(
              'Show loading',
            ),
          ),
      ),
    );
  }
}

Check this code, this is working perfectly
