App runs perfectly in debug mode but crashes on release. Tried checking ProGuard rules and minify settings. Any suggestions?
Why Does My Flutter App Crash Only in Android Release Build?

Check this out:
In one of our fintech Flutter apps at Impero IT Services, release builds were crashing due to a subtle difference in Gradle versions across dev environments. We stabilized it by explicitly pinning compileSdkVersion, Gradle & kotlin_version across CI/CD and local builds.
- Use --no-shrink to test if ProGuard is causing issues.
- Add missing proguard-rules.pro for all third-party libs.
- Make sure proper initialization in main().
- Check AndroidManifest for required permissions.
- Use flutter run --release with USB to catch errors.
- Match SDK + Gradle versions across environments.
