Unverified Breakpoint in VSCode. DebugService: Error serving requestsError: FormatException: Unsupported URI form.

[DanielJaramillo94]

Steps to reproduce

I'm learning to use Flame and I have a little project setted up. Thing is I want to use the debbuger but I can't in my main PC but in the laptop I actually can.

I have 2 breakpoints:

1. main.dart, line 5
2. pixel_adventure.dart, line 5

The execution code stops in breakpoint 1, as expected, but it doesn't stop in breakpoint 2. When I do click "Step into" when I'm on breakpoint 1, the debug console prints the next error: DebugService: Error serving requestsError: FormatException: Unsupported URI form: C:/Users/daniJ/AppData/Local/Pub/Cache/hosted/pub.dev/flame-1.17.0/lib/src/components/sprite_animation_group_component.dart

The breakpoint 2 is marked as "Unverified endpoint" everytime, as if the execution code wouldn't be able to reach it, but the project is working as expected, so the code is being reached.

Expected results

I expect the stop execution stops on breakpoints 1 and 2 when running the project in debug mode

Actual results

The execution stops only in breakpoint 1

Code sample

EDITED example to make it shorter

Code sample

Lib folder in project structure (only 3 files):

lib (folder)
main.dart
pixel_adventure.dart
components (folder)

player.dart

main.dart

import 'package:flutter/material.dart';
import 'package:pixel_adventure/pixel_adventure.dart';

void main() async {
  final game = PixelAdventure();

  runApp(
    Container(),
  );
}

pixel_adventure.dart

import 'package:pixel_adventure/components/player.dart';

class PixelAdventure {
  PixelAdventure() {
    final player = Player();
  }
}

player.dart

import 'package:flame/components.dart';
import 'package:flutter/services.dart';
import 'package:pixel_adventure/pixel_adventure.dart';

class Player extends SpriteAnimationGroupComponent with KeyboardHandler {
  @override
  bool onKeyEvent(KeyEvent event, Set<LogicalKeyboardKey> keysPressed) {
    return super.onKeyEvent(event, keysPressed);
  }
}

Hi @DanielJaramillo94
Does this issue only occur on your project with flame? If so, you can report the issue on flame repository for better support there.

Otherwise, please narrow this down and provide a completed and minimal reproducible code sample that doesn’t include 3rd party plugins or complex production code that is easier for us to investigate. Thanks!

[DanielJaramillo94]

Hello @huycozy
I already raised the issue in Flame repo (flame-engine/flame#3126) but I'm not sure if the bug is on their code, because the bug can dissapear if I just remove one import from a file.

You could check the reproducible example I set on that issue as it is much shorter, or I can paste it in here if needed. The thing is I needed to keep Flame as dependency to raise the error. 😢

[huycozy]

I would suggest you follow up on that issue to see if someone there can move it forward. I will keep this issue open, please come back once you have more information.

[spydon]

@huycozy I'm fairly confident that this has nothing to do with Flame, since it is Flutter's debugger that is giving the error.
@DanielJaramillo94 could it possibly be a broken local cache or something like that?

[vmtest888]

I ran "pub cache clean" and then "pub get" and it was also an error.

[DanielJaramillo94]

@spydon It can't be cache. I even reseted my Win11 installation (with files included).

[spydon]

And this only happens when you have breakpoints in Flame code, not when you have them in for example the counter example?

[DanielJaramillo94]

@spydon From the tests I made, happens with some breakpoints in some Flame code. In the provided example with Flame code I have 2 breakpoints and the debugger only fails on break the execution in breakpoint n.° 2.

The error might happen on some code outside Flame code but I couldn't find it.

[spydon]

I see that you have android studio installed too, have you tried it in there too?
