With flutter console we can draw a console that allows us to scan and print data as well as being able to configure its size and colors.

Add to pubspec.yaml:

dependencies:
    flutter_console_widget: ^0.0.3

• Color? consoleTextColor: color of the console text.
• FlutterConsoleController controller: console controller.
• double height: height of the console.
• Color? inputBackground: background color of the text input field.
• Color? inputTextColor: color of the text of the text input field.
• Color? scrollColor: color of the scroll bar.
• double width: width of the console.

Attributes:

• FocusNode focusNode: focus node for the text input field.
• TextEditingController inputController: controller of the text input field.
• ScrollController scrollController: controller of the scroll bar.
• Completer completer: completer object to manage the readings of the text input field.
• FlutterConsoleData value: console data object.

Methods:

• FlutterConsoleController: constructor of the class.
• show: show the console.
• hide: hides the console.
• print: write a message to the console.
• scan: reads a value from the text input field.
• clear: clears the content of the console.

import 'package:flutter/material.dart';
import 'package:flutter_console_widget/flutter_console.dart';

class HomePage extends StatelessWidget {
  HomePage({
    super.key,
  });

  final FlutterConsoleController controller = FlutterConsoleController();

  void echoLoop() {
    controller.scan().then((value) {
      controller.print(message: value, endline: true);
      controller.focusNode.requestFocus();
      echoLoop();
    });
  }

  @override
  Widget build(BuildContext context) {
    echoLoop();
    final size = MediaQuery.of(context).size;
    return Scaffold(
      appBar: AppBar(
        title: const Text('Example'),
      ),
      body: FlutterConsole(
        controller: controller,
        height: size.height,
        width: size.width,
      ),
    );
  }
