    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  listItem: {

    margin: 2,
    borderColor: '#0099A8',

Props

It accepts all the FlatList props out of which renderItem and data are the compulsory ones and has one more extra prop called offset which lets you set the offset at which new data should be added. The default value is 20 and you can change it according to your item.

Pending Tasks

• Make upward and downward scroll more smooth.
• The scroll view should work even when the content size is less than the layout measurement.
