assembler_arm64.h: 218: error: unreachable code #82278

@RussianDragon Looks similar to #64526. Are you using too many optional parameters ? If so, can you try to make them named instead of positional and see if it works ? Also, I am not sure if the fix for #64526 reached stable or not. But can you try to switch to latest master and try again to see if you still get same error ? Thanks. |

When running on iOS devices I get the following crash: When looking at |
I not using "array optional" parameters. Off course i user "parameters in braces {}". I'm afraid, if delete all braces, this is not a solution this problem I can remove the group check in the example
this removes the problem, but is not a solution too... |
Yes. I an assign events. Which are then called in mobx. Maybe there is an opportunity to see the compiled code? |

@RussianDragon as a workaround you can do the following (add a type parameter to abstract class _AbstractControl<Whatever> with StoreThis particular crash happens because offset to special hidden type arguments field overflows the instruction encoding and by adding type parameter earlier in the hierarchy you decrease this offset. We are going to provide a fix in the Dart VM. |
Thank you so much. It works! |

We will keep this issue open until we actually fix the underlying problem. |

…arge offset If the type arguments vector gets introduced in subclasses where the base classes have already many fields we may not be able to load the TAV in one instruction on ARM64.

Presumably, the fix has landed in Dart and is waiting to be rolled in https://dart-review.googlesource.com/c/sdk/+/199481. |
|
The fix has rolled into Flutter, closing this issue. |

@a-siva I am using the latest master branch of flutter but still getting kind of the same error/crash when running my app. |
|
@FelixMittermeier yes, please do report a separate issue for your problem, because this particular problem has been fixed |

Hello.
I am author package https://github.com/QuantumArt/flutter_mobx_form_validation_kit
And i have problem with "assembler arm64.h: 218: error: unreachable code" on real devices.
I have not problen on simulators (Android, iOS), i not have problem on windows, web or test... I have problem only real devices, and only on arm64... I have problem only real devices, and only on arm64...

error log
Unfortunately I was unable to create a simpler example ...
Maybe it will be easier for you if I say that while preprocessing and localizing the problem, I found the following code as the source of the problem:
final completer = Completer<List<ValidationEvent>>(); this.reactionOnValidatorDisposers.add( reaction((_) { dynamic result; if (isFirstReaction) { result = validator(this as AbstractControl) .then(completer.complete); } isFirstReaction = false; return result; }, (_) => this.lastValidationFunction()), ); return completer.future;But I don't have idea, how to correct this code.
