Observatory URL Issue

[AnasAR004]

Flutter App in Profile mode Error - No observatory URL matching to '/(Observatory listening on |An Observatory debugger and profiler on\s.+\sis available at: |The Dart VM service is listening on )((http|//)[a-zA-Z0-9:/=_-.[]]+)/' was found in the device log. Please make sure the application under test is configured properly according to https://github.com/appium-userland/appium-flutter-driver#usage and that it does not crash on startup.

Did the observatory url present on the system log/adb log?

I am getting below error log in the appium server.

Was the url actually the app was listening? Could you share the full log as GIST?

Probably you haven't done https://github.com/appium/appium-flutter-driver?tab=readme-ov-file#usage-and-requirement especially adding flutter_driver dependency

[AnasAR004]

[AnasAR004]

we have added the same but still the same issue is shown

[KazuCocoa]

Hm, then I have no idea.

Usually, an error below indicates the flutter_driver dependencies are not in the app package. Then, adding the flutter_driver deps and enableFlutterDriverExtension usually can resolve that. The integration test dependency only could cause the error afaik.

"ext.flutter.driver" is not found in "extensionRPCs" ["ext.ui.window.scheduleFrame","ext.ui.window.reinitializeShader","ext.ui.window.impellerEnabled","ext.dart.io.getHttpEnableTimelineLogging","ext.dart.io.setHttpEnableTimelineLogging","ext.dart.io.httpEnableTimelineLogging","ext.dart.io.getSocketProfile","ext.dart.io.startSocketProfiling","ext.dart.io.pauseSocketProfiling","ext.dart.io.socketProfilingEnabled","ext.dart.io.clearSocketProfile","ext.dart.io.getVersion","ext.dart.io.getHttpProfile","ext.dart.io.getHttpProfileRequest","ext.dart.io.clearHttpProfile"]

I heard that if multiple views were managed by different package, one package could include ext.flutter.driver with the flutter_driver dependency, but another one was not. Such complicated situation could happen as another possible case.

I found this "ext.flutter.driver" content load could take time. https://github.com/appium/appium-flutter-driver/pull/792 will improve the initial check.
