  • onTouchTap is implmented by react-tap-event-plugin and is used in the amazing material-ui.
  • I am using this with material-ui library and the default props for styles follows the material design pattern.
  • The structure of file describing object is:
  name: "IMG_20160813_102226.jpg",
  type: "image/jpeg",
  size: 645,
  base64: "data:image/jpeg;base64,/9j/4SzyRXhpZgAATU0AKgA...",
