Flutter app crashing after releasing on play store

[whiz-kid]

I've developed an app in flutter. It runs perfectly for ios and is live on app store. Now when I run it for android platform it runs fine both in debug and release mode. But when I create bundle and upload it on play store it crashes with following error :

java.lang.RuntimeException:

Help me understand the problem and how to fix it. Highly appreciate your help.

@whiz-kid Well, in the first place it's a typical Java-Nullpointer error, but this error comes from the plugin ImagePicker, which you are using and NOT from Flutter itself. But when I look closer into the source-code from that plugin it seems you're using a kinda old version of that plugin.

Could you post your pubspec.yaml?

Here is my pubspec.yaml

jayjah may be right, check the documentation as they migrated from 0.7.0 to null safety and your code may not be optimal

[jayjah]

Yeah, just like @Najib90 mentioned. You should first upgrade your dependencies and then look further. As of posting this comment the current version of ImagePicker is v 0.8.4+4.

@whiz-kid
Check above comments and try to upgrade dependencies and run again to see if it helps to resolve your issue.

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
Thanks for your contribution.
