Custom Formatters

• Providing custom formatters will override the default formatters.

FormattedText(
  '==This text is orange==',
  formatters: [
    ... FormattedTextDefaults.formattedTextDefaultFormatters, // To add default formatters
    FormattedTextFormatter(
      patternChars: '==', // Pattern char(s)
      style: TextStyle(color: Colors.orange),
    )
  ],
)

Context Menu Builder

To get adaptive text selection toolbar with default formatter menu items,

contextMenuBuilder: (BuildContext context,
    EditableTextState editableTextState) {
  return FormattedTextContextMenuBuilder
    .adaptiveTextSelectionToolbar(
      editableTextState: editableTextState);
}

Custom Context Menu Builder Items

• Providing custom menu items will override the default formatter items.
• Don't escape patternChars.

contextMenuBuilder: (BuildContext context,
    EditableTextState editableTextState) {
  return FormattedTextContextMenuBuilder
      .adaptiveTextSelectionToolbar(
    editableTextState: editableTextState,
    items: [
      ...FormattedTextDefaults
          .formattedTextDefaultContextMenuItems, // Default formatters
      const FormattedTextContextMenuItem(
        label: 'Orange',
        patternChars: '==',
      ),
    ],
  );
},

Or

• Use context menu button items

contextMenuBuilder: (BuildContext context,
    EditableTextState editableTextState) {
  return AdaptiveTextSelectionToolbar.buttonItems(
    anchors: editableTextState.contextMenuAnchors,
    buttonItems: [
      ...editableTextState.contextMenuButtonItems,
      ...FormattedTextDefaults
          .formattedTextDefaultContextMenuButtonItems(
              editableTextState),
      FormattedTextContextMenuBuilder
          .buildContextMenuButtonItem(
        editableTextState: editableTextState,
        item: const FormattedTextContextMenuItem(
          label: 'Orange',
          patternChars: '==',
        ),
      ),
    ],
  );
}

DEPRECATED

Use Context Menu Builder

Selection controls

To display custom selection controls,

selectionControls: FormattedTextSelectionControls(),

Modify cut / copy / paste / select all action availability using Toolbar Options

toolbarOptions: ToolbarOptions(
  cut: false,
  copy: false,
  paste: false,
  selectAll: true,
)

Custom Toolbar Actions

• Providing custom actions will override the default actions except cut / copy / paste / select all.
• Don't escape patternChars.

selectionControls: FormattedTextSelectionControls(
  actions: [
    ... FormattedTextDefaults.formattedTextToolbarDefaultActions, // To add default actions
    FormattedTextToolbarAction(
      label: 'Orange',
      patternChars: '==',
    )
  ],
)

Note

• All formatter patterns must be distinctive
