Incular Docs

Input = TextField (base-UI terminology; TextField is the compat name).

Input	Lines	Submit
`TextField` / `Input`	Single	`on_submit` + `on_changed`
`TextArea`	Multiple	`on_changed` only
`DocumentEditor`	Multiple, long documents	`on_changed` only

use incular::prelude::*;
use incular::controls_prelude::{TextArea, TextField};

fn main() {
    let app = Application::new(|_cx| {
        Container::builder()
            .padding(EdgeInsets::all(24.0))
            .alignment(Alignment::CENTER)
            .child(
                Column::builder()

                                "Bio",
                            ))
                            .placeholder("Bio").into(),

DocumentEditor looks and behaves like TextArea but lays its text out line by line with EditableText::paragraph_layout. An edit lays out only the lines it changes, so typing near the top of a file of thousands of lines costs about as much as typing at its end. Use it for source files, logs and other long documents; TextArea keeps Flutter's whole-text layout, which suits short text.

use incular::controls_prelude::DocumentEditor;

let source = std::fs::read_to_string("main.rs").unwrap_or_default();
let editor = DocumentEditor::new(TextEditingController::with_text(source))
    .size(Size::new(800.0, 600.0))
    .on_changed(|text| println!("{} bytes", text.len()));

TextFieldStyle { background, foreground, placeholder_color, border, border_focused, border_radius, padding } — all Option.
