Usage

Define a QuillEditorController to access the editor methods, pass the controller to QuillHtmlEditor Widget

  final QuillEditorController controller = QuillEditorController();

     QuillHtmlEditor(
        text: "<h1>Hello</h1>This is a quill html editor example 😊",
        hintText: 'Hint text goes here',
        controller: controller,
        isEnabled: true,
        minHeight: 300,
        textStyle: _editorTextStyle,
        hintTextStyle: _hintTextStyle,
        hintTextAlign: TextAlign.start,
        padding: const EdgeInsets.only(left: 10, top: 5),
        hintTextPadding: EdgeInsets.zero,
        backgroundColor: _backgroundColor,
        onFocusChanged: (hasFocus) => debugPrint('has focus $hasFocus'),
        onTextChanged: (text) => debugPrint('widget text change $text'),
        onEditorCreated: () => debugPrint('Editor has been loaded'),
        onEditorResized: (height) =>
        debugPrint('Editor resized $height'),
        onSelectionChanged: (sel) =>
        debugPrint('${sel.index},${sel.length}')
      ),

Define ToolBar widget and pass the same controller created for QuillHtmlEditor

   ToolBar(
        toolBarColor: Colors.cyan.shade50,
        activeIconColor: Colors.green,
        padding: const EdgeInsets.all(8),
        iconSize: 20,
        controller: controller,
        customButtons: [
        InkWell(onTap: () {}, child: const Icon(Icons.favorite)),
        InkWell(onTap: () {}, child: const Icon(Icons.add_circle)),
  ],
)

Note: toolBarConfig, if not passed to ToolBar, it will show all the Toolbar Buttons. To show only required buttons, please specify the types in the list as show below.

    final customToolBarList = [
      ToolBarStyle.bold,
      ToolBarStyle.italic,
      ToolBarStyle.align,
      ToolBarStyle.color,
    ];

    ToolBar(
     controller: controller,
     toolBarConfig: customToolBarList
    ),

We can also add custom buttons to our ToolBar as shown below

    final customButtons =  [
     InkWell(onTap: () {}, child: const Icon(Icons.favorite)),
     InkWell(onTap: () {}, child: const Icon(Icons.add_circle)),
     ];

    ToolBar(
     controller: controller,
     customButtons:customButtons
    ),

To get the html string from editor

  String? htmlText = await controller.getText();

To set the html string to editor

 await controller.setText(text);

To get the text in delta format

 await controller.getDelta();

To set the text in delta format

 controller.setDelta(deltaMap);

To insert the html string to editor

/// index is optional
/// If the index is not passed, the text will be inserted at the cursor position
await controller.insertText(text, index: 10);  

To clear the editor

  controller.clear();

  controller.enableEditor(true);
