Auto detection of crash in iOS and Android MAUI apps

Problem Statement

I have seen that other Sentry SDKs have a way of checking if the last run ended in an unhandled crash. I don't beleive this is currently possible with the MAUI SDK.

What we would do with this is popup a simple (prebaked if possible) UI that takes feedback from the user. We'd like to be able to remove any requirement for an email address from the feedback as our users need to maintain anonymity.

They may want to give is emailaddress but we do not want it as they may well be in a clinical trial and should not be sharing that with us.

Solution Brainstorm

The Cocoa SDK has support for detecting when the last run crashed:

sentry-dotnet/src/Sentry.Bindings.Cocoa/ApiDefinitions.cs

Lines 1347 to 1349 in b40a2a8

    
           // @property (copy, nonatomic) SentryOnCrashedLastRunCallback _Nullable onCrashedLastRun; 
        
           [NullAllowed, Export ("onCrashedLastRun", ArgumentSemantic.Copy)] 
        
           SentryOnCrashedLastRunCallback OnCrashedLastRun { get; set; }

That's not yet surfaced by the .NET SDK though.

Would need an alternative solution for other platforms.

See discussion thread on Discord

I believe this has been implemented already. See:

sentry-dotnet/samples/Sentry.Samples.Ios/AppDelegate.cs

Lines 56 to 59 in 3bf4c18

    
           options.OnCrashedLastRun = e => 
        
           { 
        
               Console.WriteLine(e); 
        
           };
