flutter_quill如何设置Editor中的文字为富文本

比如一个场景

在输入框中，@某某某 是一个颜色，其他文本是一个颜色

这里要注意

const QuillEditor({
    required this.controller,
    required this.focusNode,
    required this.scrollController,
    required this.scrollable,
    required this.padding,
    required this.autoFocus,
    required this.readOnly,
    required this.expands,
    this.showCursor,
    this.paintCursorAboveText,
    this.placeholder,
    this.enableInteractiveSelection = true,
    this.enableSelectionToolbar = true,
    this.scrollBottomInset = 0,
    this.minHeight,
    this.maxHeight,
    this.maxContentWidth,
    this.customStyles,
    this.textCapitalization = TextCapitalization.sentences,
    this.keyboardAppearance = Brightness.light,
    this.scrollPhysics,
    this.onLaunchUrl,
    this.onTapDown,
    this.onTapUp,
    this.onSingleLongTapStart,
    this.onSingleLongTapMoveUpdate,
    this.onSingleLongTapEnd,
    this.embedBuilders,
    this.unknownEmbedBuilder,
    this.linkActionPickerDelegate = defaultLinkActionPickerDelegate,
    this.customStyleBuilder,
    this.customRecognizerBuilder,
    this.locale,
    this.floatingCursorDisabled = false,
    this.textSelectionControls,
    this.onImagePaste,
    this.customShortcuts,
    this.customActions,
    this.detectWordBoundary = true,
    this.enableUnfocusOnTapOutside = true,
    this.customLinkPrefixes = const <String>[],
    this.dialogTheme,
    this.contentInsertionConfiguration,
    this.contextMenuBuilder,
    Key? key,
  }) : super(key: key);

这里要注意：

属性this.customStyleBuilder 不要设置，否则的话

通过QuillController的formatText设置局部字体颜色会不起作用
