componentWillMount was deprecated in 2018

[spinoza1791]

Simple change needed to MovableView.js: componentWillUnmount was deprecated in 2018

componentWillMount() { if (typeof this.props.onMove === 'function') this.state.pan.addListener((values) => this.props.onMove(values)); }

Replace with:

componentDidMount() { if (typeof this.props.onMove === 'function') this.state.pan.addListener((values) => this.props.onMove(values)); }
