import flet as ft def main(page: ft.Page): page.title = 'Flet app' page.add(ft.Text('Hello, Flet!')) ft.app(target=main)

flet --version

Debug

fix

Use ft.app(target=main) instead of ft.app(main).

affects: >=0.23.0

deprecatedThe flet build command is being replaced by flet pack in future versions.

fix

Use 'flet pack' instead of 'flet build'.

affects: >=0.84.0

gotchaRunning flet run on mobile emulator requires --ios or --android flag; otherwise defaults to web.

fix

Use 'flet run --ios' or 'flet run --android' to specify target platform.
