NullPointerException: Attempt to invoke virtual method 'boolean android.widget.FrameLayout.dispatchTouchEvent(android.view.MotionEvent)' on a null object reference

[Deleted user]

Describe the bug
NullPointerException for Android when "toBack" is set to true.

NullPointerException: Attempt to invoke virtual method 'boolean android.widget.FrameLayout.dispatchTouchEvent(android.view.MotionEvent)' on a null object reference

To Reproduce
Steps to reproduce the behavior:

1. Integrate this plugin
2. Set "toBack" to true
3. Running app
4. When opening a screen that is invoking start of camera preview and user immediately clicks on screen when camera is not finished launching, app crashes

Expected behavior

App does not crash when clicking to early on screen..

Additional context

In the CameraPreview -> setupBroadcast method we invoke fragment.frameContainerLayout.dispatchTouchEvent(event);
This will crash when fragment.frameContainerLayout is null. This is not being checked accordingly. Please, check the current method below.

I think, there should be (null != fragment.frameContainerLayout) added to the if statement.

 private void setupBroadcast() {
        /** When touch event is triggered, relay it to camera view if needed so it can support pinch zoom */

        getBridge().getWebView().setClickable(true);
        getBridge()
            .getWebView()
            .setOnTouchListener(
                new View.OnTouchListener() {
                    @Override
                    public boolean onTouch(View v, MotionEvent event) {
                        if ((null != fragment) && (fragment.toBack == true)) {
                            fragment.frameContainerLayout.dispatchTouchEvent(event);
                        }
                        return false;
                    }
                }
            );
    }

Thanks this condition fixed the issue. But I am unable to reproduce this issue. It happens sometime, I don't know why. Please comment on this thread if anyone finds the root cause.
