Execute code in x duration while app in background but not terminated
I have an app that has a timer and after it reaches <5 seconds, it will notify user that it's almost time and at the same time run some code.​However when I lock my phone, it seems the timer is stopped as well, hence no code execution.​How do I run some code in x seconds as specified by user while the app is still in the background (aka tap on home button the app goes to background but not terminated.). If the app task is ended i do not care as I won't be bothering the user.​Is this possible?

A suggestion from the community
Hey,I need some suggestions regarding the course that i would like to deign. I intend it to be the best course when looking out for a complete app experience in flutter(from UI design to backend ,API and Publishing). I would like the following suggestions:Which back-end and hosting platform to use? Either a custom back-end or AWS or vanilla GCP or even server less Firebase kind?API using Flask(I'm most comfortable with that) vs deno/any other JS framework vs PHPState management? Bloc or Provider?local persistence in SQFLite or Hive or normal Shared Preferences?Should i include principles of TDD as well?Should i also discuss evaluating the price for your product while working as a freelancer in the same series ?Also, should i encourage people to use the libraries provided by GCP etc for ML or should i encourage them to make their own and use it since they must be more flexible in the long run and dependency is removed from third parties for your product?Would appreciate it a lot for the suggestions.Thank you in advance.

Simulate a keyboard key stroke without touching the screen.
Hey all, I am working on an app in which i need to press the return/enter key. But I want flutter to do it on its own. I am currently looking for a functionality that will allow me to simulate key strokes without touching that key.

Change state of GridView from another file
Hello guys,I have this simple GridView which is in sellBook.dart:

Widget _takePicture() { return Container( margin: EdgeInsets.symmetric(vertical: 10), width: AppTheme.fullWidth(context), height: AppTheme.fullWidth(context) * 0.5, child: Container( alignment: Alignment.center, child: GridView( gridDelegate: SliverGridDelegateWithFixedCrossAxisCount( crossAxisCount: 1, childAspectRatio: 1, mainAxisSpacing: 5, crossAxisSpacing: 10), padding: EdgeInsets.all(10), scrollDirection: Axis.horizontal, children: AppData.sellImages .map((product) => sellImageCard( product: product, )) .toList()), ) ); } 

This gridview lists sellImageCard which are cards defined in an other file:

 void _settingModalBottomSheet(context){ showModalBottomSheet( context: context, builder: (BuildContext bc){ return Container( child: new Wrap( children: <Widget>[ new ListTile( leading: new Icon(Icons.camera_alt), title: new Text('Camera'), onTap: () => { getImage(), AppData.picture_count++, AppData.sellImages.add(new sellImage(AppData.picture_count, Image.asset('assets/camera.png'))), print(AppData.sellImages[AppData.picture_count].id), } ), new ListTile( leading: new Icon(Icons.camera), title: new Text('Gallery'), onTap: () => {}, ), ], ), ); } ); } } 

AS you can see when I click on a sellImageCard, I create a new card that I add to sellImages. But the gridView in sellBook doesn't update once a new card has been created. How could I update it? I guess I have to use setState but how can I access the state of a widget in an other file?Best regards

Where do you get your app design ideas?
Hi, when it comes to designing an app I always get stuck at a certain point, since I'm a programmer and I lack that "artistic" touch I find it hard to come up with a proper design, no matter what the app is about. I only know Dribble and it's nice but I thought you guys know some other sites that might help too.

How do you do i18n/l10n?
TL&DR consider easy_localization and its companion easy_localization_loader.(Longer version...)I am looking for a i18n/l10n design + solution for a project I am working on. As a new comer to Flutter and mobile development in general, I was surprised to learn that there is no officially recommended way for something I'd consider fundamental to all app design.AFAIK the closest to "official' approach is described under Internationalization on flutter.dev . To be honest, this page reads like techno soup to me. There are a lot of boiler plate code, and the examples presented isn't what I'd consider simple, scalable, and realistic. Mentioned as an option is the intl package, which seems to be popular based on down stream dependent packages on pub.dev. I looked into it and thought it is quite feature complete but still seems a little code heavy for simple usage. So I looked around and tried out a few other i18n packages, and finally I found easy_localization and it's companion easy_localization_loader.Within minutes I got it working with minimal code changes to my app. All I had to do is:add plugin to dependencyadd json file for each supported locale to my projectwrap my run app as described in the example (copy pasta below)​

import 'package:flutter/material.dart'; import 'package:flutter_localizations/flutter_localizations.dart'; import 'package:easy_localization/easy_localization.dart'; void main() { runApp( EasyLocalization( supportedLocales: [Locale('en', 'US'), Locale('de', 'DE')], path: 'assets/translations', // <-- change patch to your fallbackLocale: Locale('en', 'US'), child: MyApp() ), ); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( localizationsDelegates: context.localizationDelegates, supportedLocales: context.supportedLocales, locale: context.locale, home: MyHomePage() ); } } 

After that anywhere in my code whenever I have a localized string I just have to wrap it with tr(). e.g.

Text(tr('welcome')); // instead of Text('welcome') 

I was also surprised to find that to save a user's preferred locale to local storage is just a boolean flag. It uses shared_preferences under the hood and I verified that it works on ios and android, and gracefully fail without breaking anything in web.In the future I intend to load the resource strings remotely, and I was pleasantly surprised again that the companion easy_localization_loader offers an http loader that can be configured as an easy one liner.Looking over on the package's github page, seems like the community is very active, another good sign. The fact that it relies on intl as the underlying foundation also makes me feel better that I have access to the other features such as gender, number, datetime formatting etc.​Seeing that there aren't other post talking about this great plugin, I decided to write a post about it to raise awareness among fellow flutter enthusiasts.
