@AnOnionz I solved it:
First you need to disable that ID check in FlutterUnityPlugin.java
:
@Keep
public static void onMessage(String data) {
Log.d(String.valueOf(FlutterUnityPlugin.class), "onMessage: " + data);
try {
JSONObject jsonObject = new JSONObject(data);
int messageId = jsonObject.getInt("id");
String messageData = jsonObject.getString("data");
for (FlutterUnityView view : FlutterUnityPlugin.views) {
// --- CHECK WAS REMOVED HERE ---
view.onMessage(messageData);
}
} catch (Exception e) {
e.printStackTrace();
}
}
Then you need to change FlutterUnityView.java
to run in UIThread rather then the UnityMain:
void onMessage(final String message) {
Log.d(String.valueOf(this), "onMessage: " + message);
final Handler mHandler = new Handler(Looper.getMainLooper());
mHandler.post(
new Runnable() {
@Override
public void run() {
channel.invokeMethod("onUnityViewMessage", message);
}
}
);
}
from flutter-unity.
If I'm not mistaken, the ID outside the data object is meant to specify the view ID. Therefore, if the view with the specified ID doesn't exist, the onMessage wouldn't be triggered.
Copied from README.md
A `Message` object has the following members:
- id (
int
)A non-negative number representing the source view when receiving a message, and the destination view when sending a message. When sending a message, it can also be set to a negative number, indicating that the message is intended for any existing view.
- data (
string
)The actual message.
