FIXED: Flutter App Stuck in Release mode
Getting a Firebase PlatformException channel-error in Flutter even though Firebase isn't the real problem? This video shows you exactly how to fix it.
The error points to Firebase, but the actual root cause is a conflict with the ffmpeg_kit package. Adding the right Proguard rules resolves the channel communication issue entirely — and in this video I walk you through how to fix it in under a few minutes.
THE EXCEPTION:::
I/flutter (22526): [IMPORTANT:flutter/shell/platform/android/android_context_vk_impeller.cc(62)] Using the Impeller rendering backend (Vulkan).
E/flutter (22526): [ERROR:flutter/runtime/dart_vm_initializer.cc(40)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel: "dev.flutter.pigeon.firebase_core_platform_interface.FirebaseCoreHostApi.initializeCore"., null, null)

The Solution (Paste this in your Proguard):
#ffmpeg_kit
-keep class com.arthenica.ffmpegkit.** { *; }
-keep class org.ffmpeg.** { *; }
-dontwarn com.arthenica.ffmpegkit.**
-dontwarn org.ffmpeg.**
-keep class com.antonkarpenko.ffmpegkit.** { *; }

THE FIX — Paste this in your Proguard file:::
#ffmpeg_kit
-keep class com.arthenica.ffmpegkit.** { *; }
-keep class org.ffmpeg.** { *; }
-dontwarn com.arthenica.ffmpegkit.**
-dontwarn org.ffmpeg.**
-keep class com.antonkarpenko.ffmpegkit.** { *; }
Note: Even though the error references Firebase, the conflict originates from ffmpeg_kit being stripped during release builds. These Proguard rules prevent that and restore the platform channel connection.
