Android Vulkan Validation Layers

This is a quick guide to get Vulkan validation layers support for a Flutter application. This guide assumes that you've created the application with flutter create, otherwise the locations might vary.

1. Download the validation layers from this GitHub releases. Typically named android-binaries-1.3.231.1.zip.
2. When you unzip the file, you will see: arm64-v8a armeabi-v7a x86 x86_64
3. Copy these directories to ${FLUTTER_APP}/android/app/src/main/vklibs. The layout should look similar to:

src/main/vklibs/
  arm64-v8a/
    libVkLayer_khronos_validation.so
  armeabi-v7a/
    libVkLayer_khronos_validation.so
  x86/
    libVkLayer_khronos_validation.so
  x86-64/
    libVkLayer_khronos_validation.so

4. Add the following line to ${FLUTTER_APP}/android/app/build.gradle, android > sourceSets section: main.jniLibs.srcDirs += 'src/main/vklibs'.

5. This should enable Vulkan validation layers on your Android application.
