[Question] How to use component functions when building a View object's control tree

[una0213]

Question

When I tried using a component function to build the control tree for a View object for screen transitions, I encountered the following runtime error. Is it not possible to use a component function in this situation?

Code sample

import flet as ft

@ft.component
def view_content():
    return ft.Text('some settings...')

@ft.control
class SettingsView( ft.View ):
    def __post_init__( self, *args, **kwargs ):
        super().__post_init__( *args, **kwargs )
        
        self.route = '/settings'
        self.controls = [ view_content() ]   # RuntimeError


@ft.component
def main():
    page = ft.context.page
    def route_change():
        page.views.clear()
        page.views.append( ft.View( route="/", controls = [ ft.Text('root view') ] ) )
        if page.route == "/settings":
            page.views.append( SettingsView() )
        page.update()

    page.on_route_change = route_change
    page.go('/settings')
    
ft.run( lambda page: page.render( main ) )

Error message

RuntimeError: No current renderer is set. Call via Renderer.render(...) or Renderer.with_context(...).
