            selectedStyles : [],
            value: [getInitialObject()]
        };

        this.editor = null;
    }

    onStyleKeyPress = (toolType) => {
        this.editor.applyToolbar(toolType);
    }

    onSelectedTagChanged = (tag) => {

More Advanced TextEditor

You need to put more effort :) to use more advanced features of CNRichTextEditor such as:

• Image Uploading
• Highlighting Text
• Change Text Color

Actually we did not implement 'Toolbar buttons and menus' and 'Image Uploading Process' because it totally depends on using expo or pure react-native and also what other packages you prefer to use.

To see an example of how to implement more advanced feature of this editor please check this Link.

Also be noticed that this example is writen with expo and required 'react-native-popup-menu' package.
