Cannot input newlines into multi-line text fields

[xylix]

Description

When editing a multi-line textfield and pressing the return key or shift+return, I would expect a newline to be input. Instead focus is moved away from the input,

Code example to reproduce the issue:

import flet as ft
from flet_core import TextField
def main(page):
    textfield = TextField(min_lines=2, max_lines=4)
    page.add(
        ft.Text("Multiline text input"),
        textfield
    )
ft.app(target=main)

Describe the results you expected:

Ability to enter newlines into multi-line textfields with return or shift-return.

Needs 'multiline=True'. Try this:

import flet as ft
from flet_core import TextField
def main(page):
    textfield = TextField(multiline=True, min_lines=2, max_lines=4)
    page.add(
        ft.Text("Multiline text input"),
        textfield
    )
ft.app(target=main)

Is this identical to #1106 ?

@gbrandt I believe multiline=True is the solution.
