I have generated a responsive login page using the Flet 0.84.0 API. This implementation utilizes the updated ft.Colors and ft.alignment.Alignment namespaces to ensure compatibility with the latest framework version.
Flet Login Implementation
import flet as ft
def main(page: ft.Page):
page.title = "Secure Login"
page.horizontal_alignment = ft.CrossAxisAlignment.CENTER
page.vertical_alignment = ft.MainAxisAlignment.CENTER
page.theme_mode = ft.ThemeMode.LIGHT
page.bgcolor = ft.Colors.GREY_50
# UI Components
logo = ft.Icon(
name=ft.Icons.LOCK_PERSON_ROUNDED,
color=ft.Colors.BLUE_ACCENT_700,
size=80
)
username_field = ft.TextField(
label="Username",
prefix_icon=ft.Icons.PERSON_OUTLINE,
border_radius=10,
width=300
)
password_field = ft.TextField(
label="Password",
prefix_icon=ft.Icons.KEY_OUTLINED,
password=True,
can_reveal_password=True,
border_radius=10,
width=300
)
login_button = ft.ElevatedButton(
text="Sign In",
width=300,
height=50,
style=ft.ButtonStyle(
color=ft.Colors.WHITE,
bgcolor=ft.Colors.BLUE_ACCENT_700,
shape=ft.RoundedRectangleBorder(radius=10),
),
on_click=lambda _: print("Login Attempted")
)
# Layout Container
card = ft.Container(
content=ft.Column(
controls=[
logo,
ft.Text("Welcome Back", size=24, weight=ft.FontWeight.BOLD),
ft.Text("Please sign in to continue", color=ft.Colors.GREY_600),
ft.VerticalDivider(height=10, color=ft.Colors.TRANSPARENT),
username_field,
password_field,
login_button,
],
horizontal_alignment=ft.CrossAxisAlignment.CENTER,
),
padding=40,
bgcolor=ft.Colors.WHITE,
border_radius=20,
shadow=ft.BoxShadow(blur_radius=15, color=ft.Colors.BLACK12),
alignment=ft.alignment.Alignment(0, 0)
)
page.add(card)
if __name__ == "__main__":
ft.app(target=main)
Next steps
- Add validation logic to the
on_clickhandler of the login button. - Implement
page.on_resizedto adjust the card width for mobile viewports. - Connect the fields to a backend auth provider using the
requestslibrary.

ft.Icons,ft.Colors, andft.BoxFitnamespaces. - Automation Scripts: Includes ready-to-use Python scripts for scaffolding, migration, and building.
- Dart & Python Integration: Step-by-step guidance on bridging Flutter widgets with Python controls.
📦 Included Automation Scripts
This skill comes with powerful scripts located in the scripts/ directory:
| Script | Command | Purpose |
