A customizable toolbar to enhance your experience of writing Markdown in Flutter apps.

This plugin uses the TextField widget from Flutter (read more below). In the future, it may become independent from it to change any text, no matter where it's coming from.

About the toolbar:

  • Platform-independent
  • Responsive wrapping (+ optionally collapsable)
  • RTL support (by setting textDirection: TextDirection.rtl in your custom TextField)
  • Easy to implement
  • Uses its own parser that can be made more precise over time
  • No other dependencies apart from the Flutter widgets


First, import the package:

import 'package:markdown_toolbar/markdown_toolbar.dart';

You have 2 options:

1. Quick integration

For quick integration, simply add the MarkdownToolbar widget (which includes a TextField) and you're done:

const MarkdownToolbar(useIncludedTextField: true),

2. Custom TextField

However, if you want to use your own TextField, declare your TextEditingController and FocusNode and set them to the controller and focusNode fields respectively (for both the TextField and MarkdownToolbar widgets):

final TextEditingController _controller = TextEditingController(); // Declare the TextEditingController
late final FocusNode _focusNode; // Declare the FocusNode

void initState() {
    _controller.addListener(() => setState(() {})); // Update the text when typing
    _focusNode = FocusNode(); // Assign a FocusNode

void dispose() {
    _controller.dispose(); // Dispose the TextEditingController
    _focusNode.dispose(); // Dispose the FocusNode

// Inside a Column for instance, place the widgets and assign the fields
Column(children: <Widget>[
        useIncludedTextField: false, // Because we want to use our own, set useIncludedTextField to false
        controller: _controller, // Add the _controller
        focusNode: _focusNode, // Add the _focusNode
        controller: _controller, // Add the _controller
        focusNode: _focusNode, // Add the _focusNode

For a complete example, check out example.dart.

  • Ability to rearrange the buttons through a List (and thus remove the need for hideButton booleans, as you can simply not include the unwanted buttons inside the list)
  • Custom character support for all buttons to change the added Markdown characters on click
  • Custom button support
  • Custom function support when clicking a button (Useful for integrating things like a File Picker when inserting an Image instead of having to manually type out the path)
  • Add Emoji button
