react-native-scroll-view-keyboard-manager

React Native component which prevents inputs from being hidden by the keyboard in scroll views - iOS and Android.

Features:

• Uses a render prop (which is better than a higher order component).
• On iOS, set the bottom inset to accommodate the keyboard and scrolls to the component if needed.
• On iOS, the scroll to reveal an input is performed while the keyboard is appearing.
• On Android, changes behavior according to the soft input mode:
  • if set to adjustResize it only adjusts the scrolling for the additional offset (not done yet).
  • if set to adjustPan it sets a bottom margin on the scroll view with the same height of the keyboard (there are known issues).
• The scroll to reveal an input is performed only if the input would be hidden by the keyboard.
• The scoll is not restored to any prosition after the user dismisses the keyboard.
• On iOS, the case in which the user scrolled past the content view using the bottom inset is handled graciuscly.
• No unwanted bouncy animations.
• Simple interface, generic implementation.

Known issues

• additionalScrollOffset is not implemented yet on Android.
• On Android, the adjustPan setting of the soft input mode causes the following glitches:
  • If an input would slightly be covered by the scroll view the screen can remain slightly panned (and any present top bar might remain slightly cropped).
  • If the focused input is located at the bottom of the scroll view the screen is temporarily panned and the completely restored (animation glitch which doesn't impact usability).
