Add Middlewares to AddPagesy

[Daxexs]

• Add Middlewares to AddPagesy. which will be automatically integrated into all decorated pages.

To use Middleware in AddPagesy is very easy, you can do it in two ways (both support async):

• Function: It only supports the use before request and has as parameter data:fs.Datasy.

• Class: It has to be inherited from fs.MiddlewareRequest, which contains two very interesting methods before_request and after_request, you can use the attribute data:fs.Datasy.

Example:

import flet_easy as fs
import flet as ft

class CustomMiddleware(fs.MiddlewareRequest):
    def before_request(self):
        print("+ Before request", self.data.page.title)

    async def after_request(self):
        print("+ After request")

async def use_middleware(data: fs.Datasy):
    print("+ Use middleware before request", data.history_routes)

tools = fs.AddPagesy(
    middlewares=[CustomMiddleware, use_middleware],
)

@tools.page(route="/home", title="Tools-Flet-Easy")
async def index_page(data: fs.Datasy):
    return ft.View(
        controls=[
            ft.Text("Home page"),
        ]
    )

@tools.page(route="/test", title="Test-Flet-Easy")
def test_page(data: fs.Datasy):
    return ft.View(
        controls=[
            ft.Text("Test page"),
        ]
    )
