3. Go to the Inworld sample scene (Assets/Inworld.AI/Scenes/SampleBasic.unity) and copy all resources to the flutter-unity-widget sample scene
4. Add Inworld API key (log in using Inworld -> Studio Panel -> Log In)
5. Run a flutter-unity scene with inworld character and make sure that it reacts to your speech
6. Build the project

A common reason for 3rd party libraries to break is because some of their code is stripped out.

For example for ARfoundation on android to work, you need to specify
-keep class com.unity3d.plugin.* { *; }
in proguard to avoid missing libraries.

But you would have to figure out the exact name of the inworld libraries to do the same.

As a test to see if it is being stripped you can do these 2 things:

• Unity player settings > code stripping > minimal
• disable shrinking in the flutter build with --no-shrink.

If those 2 fix the crash, you know it is stripping.
Otherwise it might be related to missing permissions or files being unreadable because of compression.
