Kotlin compilation error in tamara_flutter_sdk versions 1.0.13-1.0.17

[officialkhairi]

Flutter build fails with Kotlin type inference error when using tamara_flutter_sdk versions 1.0.13 through 1.0.17:

e: file:///Users/khairi/.pub-cache/hosted/pub.dev/tamara_flutter_sdk-1.0.17/android/src/main/kotlin/co/tamara/sdk/util/SingleLiveEvent.kt:22:23
Type inference failed. The value of the type parameter 'T' should be mentioned in input types (argument types, receiver type, or expected type). Try to specify it explicitly.

Running Gradle task 'assembleDebug'...

Environment

• Flutter: 3.32.8
• Dart: 3.8.1
• Android compileSdkVersion: 35
• Kotlin/Java target: 17
• tamara_flutter_sdk: ^1.0.16 (also tested 1.0.13, 1.0.15, 1.0.17)

Reproduction Steps

1. Add tamara_flutter_sdk: ^1.0.16 to pubspec.yaml
2. Run flutter pub get
3. Run flutter run on Android device
4. Build fails at Kotlin compilation step

Root Cause

The issue is in SingleLiveEvent.kt line 22 where Kotlin's stricter type inference (in newer Kotlin versions) requires explicit type parameters that aren't provided in the SDK code.

Attempted Solutions

• ✅ Tried multiple SDK versions (1.0.13, 1.0.15, 1.0.16, 1.0.17) - all fail
• ✅ Added Kotlin compiler flags (-Xallow-result-return-type)
• ✅ Verified Android Gradle Plugin and Kotlin configurations
• ✅ Cleaned Flutter and Gradle caches
