Terminating app due to uncaught exception

Is this an app that you’re developing?

Yes. Building the app on flutter and has already published the Android version of it (app is live on Play Store). But can't seem to figure out what's going wrong with the iOS version

OK.

So your app is crashing due to a language exception. The backtrace looks like this:

0 CoreFoundation            … __exceptionPreprocess + 242
1 libobjc.A.dylib           … objc_exception_throw + 48
2 Foundation                … -[NSURL(NSURL) initFileURLWithPath:isDirectory:] + 0
3 Foundation                … +[NSURL(NSURL) fileURLWithPath:] + 33
4 video_player_avfoundation … -[FLTVideoPlayer initWithAsset:frameUpdater:] + 179
5 video_player_avfoundation … -[FLTVideoPlayerPlugin create:error:] + 540
6 video_player_avfoundation … __FLTAVFoundationVideoPlayerApiSetup_block_invoke.204 + 157
7 Flutter                   … __48-[FlutterBasicMessageChannel setMessageHandler:]_block_invoke + 110
8 Flutter                   … ___ZN7flutter25PlatformMessageHandlerIos21HandlePlatformMessageENSt3__110…
9 libdispatch.dylib         … _dispatch_call_block_and_release + 12

Frame 9 is the Dispatch calling your third-party runtime. Frames 8 and 7 are that runtime. I’m not sure about frames 6 through 4, but they look like some sort of plug-in that you’ve brought in to play video. In frame 4 that plug-in calls +[NSURL(NSURL) fileURLWithPath:] and passes in a nil path. This gets to frame 3 where Foundation throws the language exception.

You have to investigate where frame 4 is getting this path to find out why it’s nil.
