Build Failure Report: Missing ScreenProtectorPlugin Class During Android Compilation

[Mikeruss1418]

Summary

The Flutter Android build is failing during Java compilation due to a missing ScreenProtectorPlugin class reference generated in GeneratedPluginRegistrant.java.

Environment

• Flutter Version: 3.44
• Package: screen_protector
• Package Version: 1.5.3
• Build Target: Android
• Build Variant: DevDebug

Error Details

Build fails with the following compilation error:

C:\projects\app\android\app\src\main\java\io\flutter\plugins\GeneratedPluginRegistrant.java:114:
error: cannot find symbol

flutterEngine.getPlugins().add(
    new com.prongbang.screen_protector.ScreenProtectorPlugin()
);

symbol:
  class ScreenProtectorPlugin

location:
  package com.prongbang.screen_protector

Gradle Failure

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileDevDebugJavaWithJavac'.

> Compilation failed; see the compiler output below.

Expected Behavior

The Android build should successfully compile with the registered Flutter plugins.

Actual Behavior

The generated plugin registrant references:

com.prongbang.screen_protector.ScreenProtectorPlugin

but the corresponding Android class cannot be found during compilation.

Steps to Reproduce

1. Use Flutter version 3.44.
2. Add dependency:

dependencies:
  screen_protector: 1.5.3

3. Run:

flutter pub get
flutter run
/// not hot reload or restart. Kill the app and build again

4. Android build fails during Java compilation.

Investigation Performed

• Verified the failure occurs inside generated plugin registration code.
• Error is isolated to screen_protector plugin registration.
• The generated file contains a reference to ScreenProtectorPlugin, but the Android plugin source does not appear to provide this class during compilation.

Possible Cause

Potential mismatch between:

• Generated Flutter plugin registration
• Cached plugin artifacts
• Android implementation of screen_protector version 1.5.3

The issue may occur after dependency cache changes, plugin regeneration, or Flutter/Android tooling updates.

Impact

• Android application cannot be built.
• Development and CI builds are blocked.

Suggested Investigation

1. Verify whether ScreenProtectorPlugin exists inside:

screen_protector-1.5.3/android/src/main/java/

2. Regenerate Flutter plugin registration:

flutter clean
flutter pub get

3. Validate compatibility of screen_protector:1.5.3 with Flutter 3.44.

4. Check whether upgrading/downgrading the plugin resolves the missing class reference.
