Thanks for the video. I am getting following error at 19.30 " Null check operator used on a null value". How do we get around that. Had to add "!"before "form" in if condition.

Hi there. Could you tell me what is the best way to provide a db with questions for a quiz app? now i'm using a json file, but i want to develop an app to registrar the questions instead of type one by one in a text editor.

I am getting error
NoSuchMethidError: The method 'touppercase' was called on null.
Reciver: null
Tired calling:touppercase().
Kindly tell me how to solve this error sir?

Thank you so much for the wonderful videos. I have a quick question when you defined the _onCreateDB method you defined 2 parameters, whereas while invoking that method you didn't specify any arguments to it. Could you please explain what's the logic behind this? Thanks again!

The best tutorial video i've ever see, the way you explain it step by step is so clear. You know very well what you do, thank you so much. Already subscribed to your channel and liked your video.

Getting error : RangeError (index): Invalid value: Valid value range is empty: 0
