How to return a Widget if there are no faces (Question) #30

Closed Loopex2019 closed 5 years ago

Loopex2019 commented 5 years ago

Hi. Checking if there is no face is working great but with printing some Text to the Debug Console. But i want to return a Widget. Can i do this in the onResult ? i tried but it didn't work for me. So i tried display a Widget in the overlayBuilder by initializing a boolean value and set it to false : onResult: (List<Face> faces) { if (faces.isEmpty) { _noface = true; print('No Face'); } }, overlayBuilder: (BuildContext context) { if (_noface == true) { return _buildNoFaceText(); } return _buildDetectButtonAndTabText(); },
I initialized the boolean value on the top of the class and it's default is false. My Goal is to connect the Checking of the onResult with the overlayBuilder to render the Widget i want. Is there something wrong in my Logic Code and if there can someone tell me the Solution ?

in onResult you should use setState to update your widget

Sorry but i have another Question: How to add a CustomPainter to paint something around a Face in the onResult. I mean i had already created my own Custom Painter with the detected face size , but i just don't know how to implement it in onResult.
