Build fails after upgrade to flutter 3.0

[stingrayx]

Hello,

just wanted to let you know that there seems an issue with the latest flutter release 3.0 and this plugin.

After upgrading my flutter the build of my app using background_locator 1.6.12 gives following errors:

background_locator\android\src\main\kotlin\rekab\app\background_locator\BackgroundLocatorPlugin.kt: (25, 1): Class 'BackgroundLocatorPlugin' is not abstract and does not implement abstract member public abstract fun onNewIntent(p0: Intent): Boolean defined in io.flutter.plugin.common.PluginRegistry.NewIntentListener

background_locator\android\src\main\kotlin\rekab\app\background_locator\pluggables\InitPluggable.kt: (22, 55): Type mismatch: inferred type is BinaryMessenger? but BinaryMessenger was expected

Best regards Thomas

Just in case someone is experiencing the same issue. Seems that the fork here has already a fix for this problem!

[sterrana]

I just updated to 3.0 and this package raises a lot of errors. With the fork above a big part of warnings are resolved, but in my case I had to manually activate MultiDex and remove ! from background_locator.dart (line 34).

[Yukams]

@caiobraga do you think you could fix your branch accordingly to @sterrana's comment ?

Here is the fix for flutter 3.0

Check it out and try.

[kivocsa99]

@Alfaizkhan i can confirm that it is still not working and there is a lot of building error

@Alfaizkhan i can confirm that it is still not working and there is a lot of building error

Can you please post a build logs here.

[kivocsa99]

@Alfaizkhan iam going to build now but long story short , it first asked me to upgrade my compile and target SDK versions to 31 then there is the whole ->

Execution failed for task ':background_location:compileDebugKotlin'.

@Alfaizkhan i have not copied anything , i just ran your example in the git repo

@Alfaizkhan here is the build gradle and it is not working

[kivocsa99]

@Alfaizkhan i've cloned it another time just to check if i did smth wrong but same thing even when upgrading the compileSDKversion

[kivocsa99]

@Alfaizkhan if you are not able to produce the problem you are more than welcome to get into my pc with teamviewer or anydesk

[imsamgarg]

https://github.com/imsamgarg/background_locator

try it, fixes all flutter 3 issues

The @imsamgarg solution did it!

Added in pubspec.yaml

Hi @guistrutzki, you can also use the version 2 of the library if you want : https://pub.dev/packages/background_locator_2
