Updating changes after Hot reload in flutter?

I am rewriting my code because I have to see some changes But when I change my code and "hot reload" it does not get reflected in emulator.

Everytime I need to full restart the app

import 'package:flutter/material.dart';

Dialog leadDialog = Dialog(
  child: Container(
      color: Colors.white,
      child: Column(
        mainAxisAlignment: MainAxisAlignment.start,
        children: <Widget>[
          Padding(
            padding: EdgeInsets.all(15.0),
            child: Text(
              'Leaderboard',
              style: TextStyle(color: Colors.black, fontSize: 22.0),
            ),
          ),
          Divider(color: Colors.redAccent),
          Row(crossAxisAlignment: CrossAxisAlignment.start, children: <Widget>[
            Padding(
              padding: EdgeInsets.all(15.0),
              child: CircleAvatar(
                  radius: 30.0,
                  backgroundImage: ExactAssetImage('assets/cat.jpg')),
            ),
            Text('Neha'),
            RaisedButton(
              padding: EdgeInsets.symmetric(horizontal: 30.0, vertical: 15.0),
              textColor: Colors.black,
              child: Text(
                '546',
                style: TextStyle(),
              ),
              shape: RoundedRectangleBorder(
                  borderRadius: BorderRadius.circular(10.0)),
            ),
          ])
        ],
      )),
);

Expected: On hot reload I should be able to see the changes.

I had the very same problem. The following steps worked for me

  • Stop app
  • Uninstall it from device/emulator
  • run flutter clean
  • re run the app

If you store your widget in a variable outside the WidgetLifeCycle it would probably wouldn't render every state change. Maybe make your widget a builder method that will render every single time its parent renders.

Also read about FlutterByExample - Widget Lifecycle, Flutter Docs Widget Intro

WidgetBuilder leadDialog = (BuildContext context) => Dialog();
