[pigeon] Regression in number handing on Android #155512
Description
What package does this bug report belong to?
pigeon
What target platforms are you seeing this bug on?
Android
Have you already upgraded your packages?
Yes
Dependency versions
pigeon: ^22.4.0
Steps to reproduce
- Configure pigeons to generate
Messages.javafor Android - Add a function that takes an integer as a parameter to
messages.dart - Generate pigeons
- Implement the generated interface from
Messages.javain native plugin's kotlin source code - Call the method from Flutter
Expected results
The native function gets executed, and the integer is passed from Flutter to Kotlin
Actual results
The native function does not get executed, and instead an exception is thrown: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Long (see full log under "Logs" section)
It appears to be a regression caused by this pull request: flutter/packages#7392, which was made in response to this issue #136111
pigeon: ^21.2.0 does not suffer from such an issue
pigeon: ^22.0.0 and all versions above do suffer from such an issue
