Getting started

Add the latest version of Formatus to the pubspec.yaml file:

  FocusNode focusNode = FocusNode(debugLabel: 'formatus');
  late FormatusController controller;

void initState() {
  controller = FormatusController.fromFormattedText( text );
}

Widget build(BuildContext context) => Column( children: [
  FormatusBar(
    controller: controller,
    textFieldFocus: _formatusFocus,
  ),
  TextFormField(
    controller: controller,
    focusNode: _formatusFocus,
    minLines: 3,
    maxLines: 10 ),
  ]);

//--- Don't forget the standard dispose of the controller
void dispose() {
  controller.dispose();
}

Use cases

This section describes the use cases for Formatus.

• Position caret -> updates FormatusBar with formats at caret position
• Select a text range -> updates FormatusBar with formats from selection start
• Activate another section-format in FormatusBar -> the current section (at caret position or at start of a selected text-range) will be changed to the activated section-format
• Change an inline-format in FormatusBar -> if a text range is selected then the selected text will be updated with the new format
• Enter characters (via keyboard or by pasting from a clipboard) -> characters will be inserted at caret position. Current format settings will be applied.
• Delete characters -> if this includes one or more (requires a text-range) line-breaks then the text right of the deleted text will be integrated into the top-level node at deletion start
• To just display the formatted text use FormatusViewer

Future Enhancements

1. Add formats for lists: ordered and unordered
2. Add action to change text color
3. Add action to insert an emoji. This should become an optional add-on action similar to FormatusAnchor. Could also include converting an emoji name into emoji inline (insert into current text node).
4. Parse markdown as formatted input
5. Export formatted text in markdown format
