09 Python Visual Novel Dialogue Engine in Flet

Uses Python dataclass to create a visual novel dialogue model in Python, then use Flet use_state() to advance through the dialogue scenes and get the page to update as the index to the dialogue tuple increases. Wrap the entire game stack into a Container to enable on_click Flet behavior and trigger game state change. The game state is a simple integer that corresponds to the index of the dialogue. Once the index is updated, all components that use elements affected by the index will update on the screen. This technique avoids the use of page.update() to make the game easier to debug since the change of the index is the main way that the page updates.
