[Question]why height isn't having effect on TextField?

Question

I have a class TaskCard class with TextField but when I explicitly set its height it didn't behave as wanted to. I don't know why is this.

Code sample

from datetime import datetime
from typing import Callable
import flet as ft

from constants.constants import Pallet, WidgetStyle


class TaskCard(ft.UserControl):
    def __init__(
        self,
        title: str = None,
        description: str = None,
        is_private: bool = None,
        created_at: str | datetime = None,
        due_date: str | datetime = None,
        is_completed: bool = None,
        completed_at: str | datetime = None,
        update_function: Callable = None,
        delete_function: Callable = None,
        height: int = 280,
        width: int = 360,
        background_color: str = "red",
        **kwargs
    ):
        super().__init__()
        self.height = height
        self.width = width
        self.background_color = background_color
        self.card_container = ft.Container(
            expand=True,
            height=self.height,
            width=self.width,
            bgcolor=self.background_color,
            border_radius=15,
            padding=ft.padding.all(8),
            content=ft.Column(
                alignment=ft.MainAxisAlignment.SPACE_AROUND,
                controls=[
                    ft.Row(
                        alignment=ft.MainAxisAlignment.SPACE_BETWEEN,
                        controls=[
                            # ? Title
                            ft.Text(
                                title,
                                style=ft.TextThemeStyle.TITLE_LARGE,
                                color=Pallet.light_text_color,
                                weight=ft.FontWeight.BOLD,
                            ),
                            # ? created date
                            ft.Text(created_at, color=ft.colors.GREY_400),
                        ],
                    ),
                    # ? Description

Try changing the parameter of "min_lines" instead. You may also need to change "multiline" to True, but I can't remember.

I don't believe that TextField has the attribute height, but I could be wrong.

thank you mate! That helped a lot, just had to adjust min_lines to desired height.
