RichEditor also has methods that can be used on its ref to set:

insertImage(url: string, style?: string)
insertLink(title: string, url: string)
insertText(text: string)
insertHTML(html: string)
insertVideo(url: string, style?: string)
setContentFocusHandler(handler: Function)
blurContentEditor()
focusContentEditor()

This method registers a function that will get called whenver the cursor position changes or a change is made to the styling of the editor at the cursor's position., The callback will be called with an array of actions that are active at the cusor position, allowing a toolbar to respond to changes.

registerToolbar(listener: Function)

Example Usage:

<RichEditor
  ref={(r) => this.richtext = r}
  initialContentHTML={'Hello <b>World</b> <p>this is a new paragraph</p> <p>this is another new paragraph</p>'}
  editorInitializedCallback={() => this.onEditorInitialized()}
/>

`RichToolbar`

This is a Component that provides a toolbar for easily controlling an editor. It is designed to be used together with a RichEditor component.

The RichToolbar has one required property:

getEditor()

Which must provide a function that returns a ref to a RichEditor component.

This is because the ref is not created until after the first render, before which the toolbar is rendered. This means that any ref passed directly will inevitably be passed as undefined.

Other props supported by the RichToolbar component are:

actions

An array of actions to be provided by this toolbar. The default actions are:
- actions.insertImage
- actions.setBold
- actions.setItalic
- actions.insertBulletsList
- actions.insertOrderedList
- actions.insertLink
- actions.keyboard
- actions.setStrikethrough
- actions.setUnderline
- actions.removeFormat
- actions.insertVideo
- actions.checkboxList
- actions.undo
- actions.redo
onPressAddImage Functions called when the addImage actions are tapped.
onInsertLink Logic for what happens when you press on the add insert link button
disabled
Boolean value to disable editor. The default value is false.
iconTint
unselectedButtonStyle
selectedIconTint
selectedButtonStyle
disabledIconTint
disabledButtonStyle

These provide options for styling action buttons.
iconSize

Defines the size of the icon in pixels. Default is 50.
renderAction

Altenatively, you can provide a render function that will be used instead of the default, so you can fully control the tollbar design.
iconMap

RichTextToolbar comes with default icons for the default actions it renders. To override those, or to add icons for non-default actions, provide them in a dictionary to this prop.

Example Usage:

const richText = React.createRef() || useRef();
<RichToolbar editor={that.richText}/>

With Custom Action:

To define your own custom action:

Send your action name as string in the actions array.
Include an icon for it with the iconMap
Add a function prop with the same action name to be called on tap

<RichToolbar
    editor={that.richText}
	actions={[
		actions.setBold,
		actions.setItalic,
		actions.insertBulletsList,
		actions.insertOrderedList,
		actions.insertImage,
		'customAction',
	]}
	iconMap={{
		customAction: customIcon,
	}}
	customAction={this.handleCustomAction}
/>
