How can I get my flutter video player to work for Chrome Web, correctly

Question

I am getting videoplayer overflow. How do I resize my video player, so it correctly works. Error message "A RenderFlex overflowed by 93 pixels on the right" during window resizing.

    controller.setVolume(_volume);

Answer 1

solution: I used SingleChildScrollView to solve the horizontal and vertical renderflex overflow errors. I changed the Consumer to use => notation rather than { return notation.
