Exception while testing
Closed this issue · 8 comments
I am getting this exception when testing my application with your navigation included. Which does not happen if I use a different one. Yet, I couldn't figure out the issue. The dispose() method is not getting called in the CostumeNavigationBarState when I debug it. Since, I am new to flutter you might have a better idea, where this comes from.
══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
The following NoSuchMethodError was thrown while finalizing the widget tree:
The method 'dispose' was called on null.
Receiver: null
Tried calling: dispose()

@JonathanIsCodeing Thanks for using my package. Can you please send me a code example of how you using this navigation bar so I can locate the issue?
I made a repo with the code part which is causing this issue:
example code
@JonathanIsCodeing Thanks, I will check it and locate the issue.
@JonathanIsCodeing I'm sorry, based on your example, I'm not able to reproduce the error, can you please tell me the process how you produce the error?
@rickywen911 It happens when I run the example test I created.
Otherwise the code runs fine in the app.
@JonathanIsCodeing Hi, I have located the issue, it seems that when run test_widget, the didUpdateWidget method is not getting called. So it will generate a null point exception. I will fix it in the new version.
Fixed, close for now.
Thank you for the effort!
