Run the app¶

To run the application we use an object method already instantiated by FletEasy (you can customize the parameters of method according to your needs :) .

Methods¶

run¶

FletEasy run

Use with fastapi¶

Available from version 0.2.8

Instead of using app.run(fastapi):

app.get_app()

To get the main of the app and be able to add Fastapi to it.

run fastapi

Export asgi app¶

run fastapi

Available from version 0.2.8

Use `Flet-Easy` in an existing app¶

Now Flet-Easy can be used within the main function of the app, this is a very favorable characteristic since it can be able to use Flet-Easy in an application already exists or adapt it according to code writing preferences.

New method to use app.start(page)

Note: You can use all existing features in Flet-Easy.

main.py

import flet as ft
import flet_easy as fs

def index_page(data: fs.Datasy):
    return ft.View(
        controls=[
            ft.Text("Home - app", size=90),
            ft.ElevatedButton("Go to About", on_click=data.go("/about")),
        ],
        vertical_alignment="center",
        horizontal_alignment="center",
    )

def about_page(data: fs.Datasy):
    return ft.View(
        controls=[
            ft.Text("About - app", size=90),
            ft.ElevatedButton("Go to Home", on_click=data.go("/")),
        ],
        vertical_alignment="center",
        horizontal_alignment="center",
    )


def main(page: ft.Page):
    page.title = "Flet-Easy - app"

    app = fs.FletEasy()
    app.add_routes(
        add_views=[
            fs.Pagesy("/", index_page, title="Home"),
            fs.Pagesy("/about", about_page, title="About"),
        ]
    )
    app.start(page)

ft.app(target=main)

Get the app created by `Flet-Easy`¶

Although this function already exists through the use of the parameter fastapi=True of the run() of Flet-Easy and is usually very confined, so the best way to understand the code and that has better legitivity would be better to use the new method get_app() of Flet-Easy.

New method to use app.get_app()

Note: You can use all existing features in Flet-Easy.

main.py

import flet as ft
import flet_easy as fs

app = fs.FletEasy()

@fs.page("/", title="Home")ssss
def index_page(data: fs.Datasy):
    return ft.View(
        controls=[
            ft.Text("Home - app", size=90),
            ft.ElevatedButton("Go to About", on_click=data.go("/about")),
        ],
        vertical_alignment="center",
        horizontal_alignment="center",
    )

@fs.page("/about", title="About")
def about_page(data: fs.Datasy):
    return ft.View(
        controls=[
            ft.Text("About - app", size=90),
            ft.ElevatedButton("Go to Home", on_click=data.go("/")),
        ],
        vertical_alignment="center",
        horizontal_alignment="center",
    )

## get app and run it
ft.app(target=app.get_app())

customize as it is executed¶

run view

Possible errors¶

build web¶

If there are problems in build web

Use:

main.py v0.2.7

import flet as ft

ft.app(app.run(fastapi=True))

main.py v0.2.8

import flet as ft

ft.app(app.get_app())

build windows¶

If there are problems in build windows

remove print() from Python if used in 'add_middleware' functions.
