I have developed an PWA with flutter and Provider as state management. API calls happens but app interface not updated. It is Ok on apk version.
I am confused why interface not updating after api responses is ready.

I have designed a mobile application using flutter, I have seen that it is compatible with the web and I would like to know how to migrate my already designed application to the web environment, I know that I must take into account the compatibility with the dependencies that I have used and already reviewed.
At the moment I have carried out the following process, but all it does is create a folder with few elements that when executed, the browser opens with a blank page, the flutter logo and a blue appbar. What procedure am I missing?
flutter config --enable-web
flutter create.
flutter run -d chrome
I am new to flutter programming. I want to create a flutter web app which can be run in web view in a Flutter desktop application for all desktop platforms (Linux, Windows and MacOS). The web-app will be running on the main thread. And desktop specific tasks will be run on an isolate. The web app will be the UI and would mainly be using cloud firestore and mostly be listening to document or collection changes and communicate the changed data back to the isolate.
Is the web-app on a Flutter Desktop application possible to do ? And will I be needing to "hosting" the web page to used in a web_view ?
And will I be able to communicate with the web-app from the isolate with the usual Isolate communications ?

Currently Flutter doesn't have desktop support for platform views, which means you can't have an inline webview. You could use a full-window webview with no Flutter UI, but then it's not clear what value you would get from having the desktop host be a Flutter application.
And will I be able to communicate with the web-app from the isolate with the usual Isolate communications ?
If you are expecting to be able to communicate directly between the isolate of the Flutter desktop host and the Flutter web application, no. You would be subject to all of the standard limitations of using a webview, which means any communication in or out would have to go through JavaScript. The fact that the host app is a Flutter app would be essentially invisible to the web app, and similarly in the other direction, because you would be running two completely unrelated instances of the Flutter engine and Dart VM (one compiled to native code and one compiled to JS).
I'm implementing AppCheck in my app in order to prevent bad access to Firestore. I activated the service in Firebase Console and add this line await FirebaseAppCheck.instance.activate(); after Firebase initialization.
Now, if I try to access Firestore in my app through emulator it logs PERMISSION DENIED.
How could I develop updates for my app and continue testing while AppCheck is enabled?
After you have registered your app for App Check, your app normally won't run in an emulator or from a continuous integration (CI) environment, since those environments don't qualify as valid devices. If you want to run your app in such an environment during development and testing, you can create a debug build of your app that uses the App Check debug provider instead of a real attestation provider.
Refer documentation Flutter app Check details.
However, as per the documentation, the debug provider does not currently have a Dart API; you'll need to apply the changes separately for each of your platforms.
You may check the App Check debug provider available for other platforms like Apple, Web and Android.
i'm making a e-commerce app with Android and Web Flutter, but, when i deploy the web app in IIS, a widget don't update. When i run on VSCode, they work as well. Android work's.
The trouble is only in Iis web Flutter. The data change, but not the widget.
I found the solution, the bug isn't in IIS, i created a new provider for the action and all runs ok.
Is it possible to build a http server in flutter mobile app but like Android service, a background process to work constantly?
I found a solution to add a http server to flutter app 1 but it is not as a background process.
