flet-navigator 1.0.1

Navigator for Flet.

Simple and fast navigator (router) for Flet (Python) that allows you to create multi-page applications in one page!

Using Example:

from flet import app, Page, Text, FilledButton, TextThemeStyle

from flet_navigator import FletNavigator, Any, ROUTE_404

from random import randint


# Main page content.
# page - Current page,
# navigator - With this you can navigate to other pages,
# args - Arguments sent from other page.
# Using these all typehints is optional.
def main_page(page: Page, navigator: FletNavigator, args: tuple[Any]) -> None:
   page.add(Text('Main Page!', style=TextThemeStyle.DISPLAY_MEDIUM))

   if args:
      page.add(Text(f'Message from {args[0]}: {args[1]}.'))

   page.add(
      FilledButton(
            'Navigate to second page!',

            on_click=lambda _: navigator.navigate('second_page', page, ('main page', 'Hello from main page!')) # Navigate to 'second_page', and send greetings from main page as arguments!
      )
   )

   page.add(
      FilledButton(
            'Navigate to really_non_existent_page!',

            on_click=lambda _: navigator.navigate('really_non_existent_page', page) # Navigate to non-existent page. Will result route_404.
      )
   )

# Second page content.
def second_page(page: Page, navigator: FletNavigator, args: tuple[Any]) -> None:
   page.add(Text('Second Page!', style=TextThemeStyle.DISPLAY_SMALL))

   page.add(Text(f'Message from {args[0]}: {args[1]}'))

   page.add(
      FilledButton(
            'Navigate to main page!',

            on_click=lambda _: navigator.navigate('/', page, ('second page', randint(1, 100))) # Navigate to main page, and send random number as arguments!
      )
   )

# 404 page content.
def route_404(page: Page, navigator: FletNavigator, args: tuple[Any]) -> None:
   page.add(Text('How did you get here? There is no page like this registered in routes...'))

   page.add(
      FilledButton(
            'Navigate to the main page until it is too late...',

            on_click=lambda _: navigator.navigate('/', page) # Navigate to main page.
      )
   )

# Main function. Being used only for routing.
def main(page: Page) -> None:
   # Initialize navigator.
   flet_navigator = FletNavigator(
      {
            '/': main_page, # Specify main page,
            'second_page': second_page, # Specify second page,
            ROUTE_404: route_404 # Specify 404 page (optional).
      }, lambda route: print(f'Route changed!: {route}') # On route changed handler (optional).
   )

   flet_navigator.render(page) # Render main page.

app(target=main) # Run main fuction.

There is no documentation, or more examples, because you can use FletNavigator just by researching this small example! Also every function, and class field has own docstring.

This example will be updated in next releases to keep everything up to date.
