decomposer

Gradle Plugin that allows you to decompile bytecode compiled with Jetpack Compose Compiler Plugin into Java and check it

How to use

Run build

> Task :uicomponent-compose:compileDebugKotlin
DecomposerPlugin: decomposed in /Users/takahirom/git/.../uicomponent-compose/build/decompile

Now, you can check the Java code in build/decompile

   @Composable
   private static final void AudioControlButton(final Modifier modifier, final boolean isVisible, final boolean isPlayingPodcast, Composer $composer, final int $changed) {
...
      if (($dirty & 731 ^ 146) == 0 && $composer.getSkipping()) {
         $composer.skipToGroupEnd();
      } else if (isVisible) {
         $composer.startReplaceableGroup(445067107);
         ComposerKt.sourceInformation($composer, "");
         Painter var6;
         if (isPlayingPodcast) {
            $composer.startReplaceableGroup(445067139);
...
