novident_editor_rich_text 1.0.2

Rich text paragraph rendering for Novident Editor — widget, selection mixin, and abstract editor config. Usable without the full editor for lightweight node rendering.

Novident Editor Rich Text

Paragraph rendering widget for the Novident Editor. NovidentRichText, DefaultSelectableMixin, and abstract configuration interfaces.

Features

• NovidentRichText — the primary paragraph-rendering widget. Renders RichText from node deltas, resolves styles through NovidentEditorStyles.maybeOf(), and provides cursor/selection rect measurements via SelectableMixin.
• DefaultSelectableMixin — proxy mixin that wraps a forward SelectableMixin with coordinate offset shifting (used by list items, quotes, and nested blocks).
• RichTextEditorConfig — abstract interface (12 getters) that replaces the EditorState dependency. Any object implementing this interface can drive NovidentRichText.
• RichTextAttributes — extension on Attributes for reading delta formatting (bold, italic, underline, strikethrough, colour, background, href, font family, font size, code, auto-complete).
• Lightweight — depends only on novident_editor_document, novident_editor_core, novident_editor_styles, novident_editor_selection, and Flutter. No editor services or infrastructure.

Getting started

Add to your pubspec.yaml:

dependencies:
  novident_editor_rich_text: <latest>

Usage

Basic paragraph

import 'package:novident_editor_rich_text/novident_editor_rich_text.dart';

NovidentRichText(
  node: paragraphNode,
  delegate: this,               // your SelectableMixin
  editorConfig: myConfig,       // implements RichTextEditorConfig
);

Implementing RichTextEditorConfig

import 'package:novident_editor_rich_text/novident_editor_rich_text.dart';

class MyConfig implements RichTextEditorConfig {
  @override double get textScaleFactor => 1.0;
  @override double? get firstLineIndentFallback => null;
  @override Color get cursorColor => Colors.black;
  @override Color get selectionColor => Colors.blue.withValues(alpha: 0.2);
  @override double get cursorWidth => 2.0;
  @override TextSpanDecoratorForAttribute? get textSpanDecorator => null;
  @override NovidentTextSpanOverlayBuilder? get textSpanOverlayBuilder => null;
  @override bool get enableAutoComplete => false;
  @override NovidentAutoCompleteTextProvider? get autoCompleteTextProvider => null;
  @override TextStyleConfiguration get textStyleConfiguration => const TextStyleConfiguration();
}

DefaultSelectableMixin

class _MyListItemState extends State<MyListItem>
    with SelectableMixin<MyListItem>, DefaultSelectableMixin<MyListItem> {

  @override
  SelectableMixin<MyListItem> get forward =>
      forwardKey.currentState as SelectableMixin<MyListItem>;

  @override
  double baseOffset() => 24.0; // bullet/number width

  // All SelectableMixin methods are delegated to `forward` with
  // coordinate offset adjustment.
}

RichTextAttributes

final attrs = node.delta?.first.attributes ?? {};
print(attrs.bold);        // true / false / null
print(attrs.italic);
print(attrs.textColor);   // '#000000'
print(attrs.fontSize);    // 12.0
print(attrs.href);        // 'https://example.com'
