What would be the best way to apply turn by turn navigation like google maps?
It looks like a lot of people don't like the google maps plugin, so I've looked at mapbox and leaflet. Are there any other options I should consider? Which plugin would you recommend I use?

Anyone use WidgetsApp instead of Material or Cupertino?
If I want to make a fully custom app with my own button styles and whatnot, how would I use WidgetsApp, does it provide zero styling for the widgets?Also, semantically, should I use a button component for example rather than a Container with an onTap function, even though I don't want the default styling that comes with a Material or Cupertino button?

<b>State of integration tests automation in Flutter</b>
I'm currently struggling with integration tests automation. The flutter_driver (see <a href="https://flutter.dev/docs/cookbook/testing/integration/introduction">official doc</a>) is great as long as you work locally but things get more complex when running it on CI with real devices (provided by services like App Center, AWS Device Farm, etc.).
For my job, I've gathered all information I could find and wrote a doc, no conclusion, just a description of the state of the art. I thought it would be nice to share in this sub since there are a lot of unanswered posts about this topic (<a href="https://www.reddit.com/r/FlutterDev/comments/cakor8/testing_flutter_for_different_devices/">here</a>, <a href="https://www.reddit.com/r/FlutterDev/comments/dxhxgx/is_there_a_test_lab_option_for_flutter_apps/">here</a> or <a href="https://www.reddit.com/r/FlutterDev/comments/davkxk/firebase_test_lab_flutter_driver/">here</a>). Feedback welcome!----------------------The tricky partThere are some well-established tools for integration test automation:Expresso (Android)XCUITest, Earl grey (iOS)Appium (cross-platform, it’s basically Selenium for mobile).Those tools are native and can access (and control) native components by their keys. Because Flutter has it own native view with everything drawn in it. Those tools are no use for a Flutter app.That’s why the Flutter team came up with a Flutter equivalent: flutter_driver. Problem is: most of the device testing services don’t support this specific tool.AWS Device Farm + SylphThe author of <a href="https://github.com/mmcc007/sylph">Sylph</a> managed to use flutter_driver to run the integration tests on real devices on both iOS and Android.Sylph repo: <a href="https://github.com/mmcc007/sylph">https://github.com/mmcc007/sylph</a>Codemagic CI blog post about Sylph: <a href="https://blog.codemagic.io/flutter-ci-cd-with-codemagic-sylph-aws-device-farm/">https://blog.codemagic.io/flutter-ci-cd-with-codemagic-sylph-aws-device-farm/</a>However, when taking a closer look how it works, it appears that the lib relies on a hack, a comment in the code mentions this StackOverflow question: <a href="https://stackoverflow.com/a/53328272/769006">https://stackoverflow.com/a/53328272/769006</a>The app sent to AWS is actually a dummy Python application. This somehow allows to override the test command, that how we can run the “flutter driver” command.From the author on the library himself:I was able to get flutter driver working on AWS Device Farm by shoe-horning it into an Appium (python) test... kinda like a trojan horse.Source: <a href="https://github.com/flutter/flutter/issues/7087#issuecomment-466634265">https://github.com/flutter/flutter/issues/7087#issuecomment-466634265</a> (1 year ago)Firebase Test LabIt seems like there is the beginning of an official support from the Flutter team with the <a href="https://pub.dev/packages/e2e">e2e</a> package, even it is still suboptimal (Android only, no support for Robo scripts).Open issues:Official support <a href="https://github.com/flutter/flutter/issues/11718">https://github.com/flutter/flutter/issues/11718</a>Robo scripts support: <a href="https://github.com/flutter/flutter/issues/36681">https://github.com/flutter/flutter/issues/36681</a>I also found the discontinued <a href="https://pub.dev/packages/instrumentation_adapter">instrumentation_adapter</a> package but it’s the predecessor of the e2e package mentioned above (there is an obvious similarity when comparing the 2 readme files).SauceLabsThe only working example I found concerning SauceLabs is from the author of Sylph. It is built on TravisCI and use only an Android simulator. It’s more a PoC and it is not very useful since a simulator can be directly accessible from TravisCI where flutter driver can be used.TravisCI config: <a href="https://travis-ci.com/github/mmcc007/test_flutter_saucelabs/jobs/180159349/config">https://travis…

Dice Game Flutter(8th/90 Days Challenge)
Dice Game App is my 8th App in this 90 Days Challenge. In this app, basically there are 2 dices will be present on the screen and when the user will click them it will generate the random number from 1 to 6.I had learnt about Expanded, Flat Button and how to differentiate between the Stateful and Stateless widget properties with each other. I had also got to know about the Math properties related to dart. I had created a function named to automate the task of generating random numbers and changing the picture.Features need to be implemented further are as follows:Exception Handling.Thinking about changing the overall UI( of Material App) after every iteration.When both the numbers will be the same, there should be a pop message should be generated.Some kind of scoring should be present in this application.If anyone wants to take a look and give some feedback about the app/the code, it would be really nice :). Pls star and fork the main repo, if you will find it interesting, I will create more advanced apps in the future. Thanks, r/FlutterDev for motivating me this journey and helping me to become a better developer.Deployed Version of the Project: linkhttps://github.com/irahulcse/A-Complete-Guide-To-Flutter#008---dice-game-flutter

Replace native Apps in Google Play and Apple App Store with Flutter Apps over store update mechanisms. Additional keep applications' keys in the keystore/keychain.
Hello,we currently have an application developed native for Android (Kotlin/Java) and iOS (Swift/Objective C) which relies on the Android Keystore and Apple Keychain.This Application is distributed over the App-Stores (Goole Play/ Apple App Store).Now we want to develop our Application completely new with Flutter. We need to access the keystore and keychain also with this application (should be doable).Is it also possible, that we will publish our new application as an update to the App stores and access/use the previously, with the native apps generated keys? Do you have expirience with replacing native Apps with flutter apps in the App stores? What do we need to pay attention to?Thank you for your help :)

Dynamic screens
I’m just beginning with Flutter and I’m trying to work out if it’s possible to dynamically build a screen. Hoping some experts in here can point me in the right direction.I have an app in vanilla JavaScript with JQuery that I’m thinking about rewriting using Flutter.The main part of the app has a single page which dynamically generates its components and interactivity at run time.It loads a JSON file which specifies deploy X component Y times with this data. A JavaScript file for that component is then loaded, the component is created on screen with the appropriate data and then the next component until all components are created and the screen is complete.There’s around 50 different component types that can be used on a page. Each page only uses a single component type but it may be used multiple times. There’s around 5000 pages.In Flutter, I could see how each component could be a widget but could I create the instance of the component at run time? Would I have to have every possible component (50 ish) imported to the page regardless of whether it is used on that page?In my vanilla JavaScript version, the component would only be loaded if it’s used in the page and then each required instance would be deployed to the page at runtime.I’m just not sure if this is possible in Flutter or how you might go about it. Or even if there is an alternative approach that would better fit into the Flutter approach.Thanks for any thoughts you may have on this.

Best-practice for moving documents between collections (in Firebase, but this question is more theoretical)?
Hi all, this a theoretical/best-practice question.Say I'm making a fancy to do list, where each task (with a lot of complicated steps per task) are each their own document.I also have a bunch of collections, each collection represents a different status of the tasks inside of it. For example, "collection_unassigned", "collection_assigned", "collection_complete".As document_task moves through a workflow, I'd like to move it between different collections so that I can see, at a glance by viewing the collections in Firestore, how many tasks I have in each collection.Is this acceptable practice? Putting theory into practice, what is a better way to approach my above goal? Each document having a field that says what status it currently has?(My concern is that if I leave all document_tasks in the same collection, it will quickly become large and slow, as I'm dealing with tens of thousands of document_tasks.)
