RxBle.stopScan() crashes on Flutter 1.7.8 #8

Closed gblach closed 5 years ago

gblach commented 5 years ago

Earlier I used RxBle with Flutter 1.5.3 and everything works correctly. After I updated Flutter to current stable release, RxBle crashes every time I wanna stop scanning.

devxpy commented 5 years ago

Thanks for the report! Sorry I've been out travelling, and not able to help you. Get back as soon as possible.

devxpy commented 5 years ago

Here's the bug report upstream - https://github.com/flutter/flutter/issues/34993

01xJoao commented 5 years ago

@devxpy any update on this ?

devxpy commented 5 years ago

No. Downgrade flutter, and wait for flutter to fix this.

01xJoao commented 5 years ago

whats the last version that this works in ?

devxpy commented 5 years ago

This is the offending commit - https://github.com/flutter/engine/pull/8830, so I guess anything before May 4th?

ssteveli commented 5 years ago

I'm curious @devxpy , why is this issue a "wait for flutter to fix this"? It seems like the contract has changed for android plugins like this and I see other plugins adapting to the change? Maybe you can help me understand a bit further?

Thanks!

devxpy commented 5 years ago

I'm looking for an official response from the team, on that issue. Plus, I don't want to spend time on a breaking change that is not really our fault.

If you are so inclined yourself, I would gladly accept the PR :)

ssteveli commented 5 years ago

https://github.com/pycampers/flutter-plugin-scaffold/pull/1

This solved the problem for me, my application is now working against on Flutter 1.7.8+hotfix.4.

devxpy commented 5 years ago

Thanks, @ssteveli. Released your fixes in v0.5.5.

devxpy commented 5 years ago

@gblach Please close the issue if resolved.

ssteveli commented 5 years ago

Sorry for the churn, day job is keeping me overloaded. I have one more minor fix related to this that I'll try to PR asap if that impacts the decision to "resolve" or not.

devxpy commented 5 years ago

Story of open source developers :( - GitHub stars won’t pay your rent

01xJoao commented 5 years ago

This problem is fixed, this should be closed.
