是否有一个函数可以在我的gutenberg块中创建自定义块？

const { registerBlockType } = wp.blocks;

registerBlockType( 'my-plugin/my-custom-block', {
    title: 'My Custom Block',
    icon: 'smiley',
    category: 'common',
    attributes: {
        content: {
            type: 'string',
            source: 'html',
            selector: 'p',
        },
    },
    edit: ( props ) => {
        const { attributes, setAttributes } = props;
        const { content } = attributes;

        const onChangeContent = ( newContent ) => {
            setAttributes( { content: newContent } );
        };

        return (
            <div>
                <h2>My Custom Block</h2>
                <textarea value={ content } onChange={ onChangeContent } />
            </div>
        );
    },
    save: ( props ) => {
        const { attributes } = props;
        const { content } = attributes;

        return (
            <p>{ content }</p>
        );
    },
} );
