Reddit: A few questions about adopting Flutter.
I have an iOS and Android app that use bluetooth and save a lot of data points on a Realm database locally. How does Flutter do running in the background with both platforms? I know Realm is not available for Flutter but could I build an extension on Android and iOS to read and write to it? Would that be too slow? What types of functions should or should not be handled by the native framework instead of Flutter? Thanks guys!

Reddit: Can't get first Flutter app running
I've followed along the instructions on Get Started: Install on Linux but once I'm at the point of trying to run the initial app, it fails with a gradle error regarding a file called 'intellij-core.jar'.There's a Stack Overflow question similar to mine here but none of the answers work for me.I've tried on both Linux and Windows but it seems to be a showstopper. Not sure how to proceed.Flutter doctor says I have everything set up correctly, and I'm using the latest version of Android Studio.

Reddit: Flutter iOS OAuth Implementation
I've been struggling with implementing the OAuth flow inside my Flutter app. At a low level, I'm trying to use the Quickbooks API to push some customer data to. Right now the app is hosted on Firebase.It's my understanding that the Redirect URI in the OAuth Flow for a mobile application needs to be some kind of deep link inside the application, which leaves iOS's Universal Links, and Firebase Dynamic Links (just another implementation of Universal Links for a Firebase app).I've been able to use both of these methods to successfully link back to my app using Safari within the iOS emulator. However, when I use that app link as a Redirect URI in the OAuth Flow, the redirection never happens. I get to the point of allowing Quickbooks access to my app in the Safari Webview, and I can see the browser "make an effort" to redirect (app redirect URL flashes quickly), but it never actually makes that hand off, leaving me unable to parse the returned URI.Does anybody have any guidance on what could possibly be happening here?
