[Question]How to remove margins in ft.View?

[dvemba]

Question

Hello, I'm learning flet and I have some difficulties removing the margins inside a ft.View(). When I added ft.NavigationRail to ft.View, a margin appears around ft.NavigationRail, that is, any Control I add:

Please someone help me.

Code sample

import flet as ft
from flet_route import path,Routing,ViewNotFound
from source.views.Login_Screen import Login_Screen
from source.views.Painel_Screen import Painel_Screen



def index_view(page,params,basket):
    return ft.View(
        "/",
        [
            ft.Row(
                [
                    ft.NavigationRail(bgcolor="red",
                        width=200,
                        selected_index=0,
                        label_type=ft.NavigationRailLabelType.ALL,
                        # extended=True,
                        min_width=100,
                        min_extended_width=400,
                        leading=ft.FloatingActionButton(icon=ft.icons.CREATE, text="Add"),
                        group_alignment=-0.9,
                        destinations=[
                            ft.NavigationRailDestination(
                                icon=ft.icons.FAVORITE_BORDER, selected_icon=ft.icons.FAVORITE, label="First"
                            ),
                            ft.NavigationRailDestination(
                                icon_content=ft.Icon(ft.icons.BOOKMARK_BORDER),
                                selected_icon_content=ft.Icon(ft.icons.BOOKMARK),
                                label="Second",
                            ),
                            ft.NavigationRailDestination(
                                icon=ft.icons.SETTINGS_OUTLINED,
                                selected_icon_content=ft.Icon(ft.icons.SETTINGS),
                                label_content=ft.Text("Settings"),
                            ),
                        ],
                        on_change=lambda e: print("Selected destination:", e.control.selected_index),
                    ),
                    ft.ElevatedButton("Voltar",on_click=lambda e: page.go('/login')) 
                ],expand=True
            )
        ]
    )

def main(page: ft.Page):

    page.theme_mode = "light"
    
    app_routes = [
        path(url="/", clear=True, view=index_view),
    ]

    Routing(
        page=page, # Here you have to pass the page. Which will be found as a parameter in all your views
        app_routes=app_routes, # Here a list has to be passed in which we have defined app routing like app_routes
        not_found_view = ViewNotFound # If you want that there should be a different view call when no path matches, then you can pass that view here. otherwise no need to give it it will call ViewNotFound by default
        )
    page.go(page.route)
ft.app(target=main)

As incredible as it may seem, after sending my question, I realized that instead of being a margin it could be a padding, I decided to do a test and I got it.

Exactly: page.padding=0
