如何让Android返回一个内部类对象来颤动

Question

我使用 Flutter 调用 Android 第三方 SDK，但我不知道如何从 Flutter 的onCallback()方法中获取值 'i' 和 'info'。

代码

public static void registerWith(PluginRegistry.Registrar registrar) {
    channel = new MethodChannel(registrar.messenger(), CHANNEL);
    LivenessPlug instance = new LivenessPlug(registrar.activity());
    channel.setMethodCallHandler(instance);
}

@Override
public void onMethodCall(MethodCall methodCall, MethodChannel.Result result) {
    if (methodCall.method.equals("getLivenessResult")) {
        try {
            getLivenessResult();
            result.success();
        } catch (Exception e) {
            e.printStackTrace();
            Toast.makeText(activity, e.toString(), 2000).show();
        }
    }
    else {
        result.notImplemented();
    }
}

public void getLivenessResult() {
    OctopusLivenessManager.getInstance().
        detectLiveness(activity, new OctopusLivenessCallback() {
            @Override
            public void onCallback(int i, OctopusLivenessInfo info) {
                if (i == 0) {
                    Log.e("result", info.verificationPackage);
                }
                Toast.makeText(activity, i + "", Toast.LENGTH_SHORT).show();
            }
        });
    }
 }
