How to use KeyboardAvoidingView with FlatList?

I have a FlatList component with an Input inside each row. When I select the input I want it to scroll up above the keyboard.

My code:

return (
    <KeyboardAvoidingView behavior='padding' style={{ flex: 1 }} >
    <FlatList
      style={{ flex: 1, backgroundColor: '#fff' }}
      data={ds}
      renderItem={({ item }) => <ListItem data={item} />}
      ListFooterComponent={this.renderButton}
    />
  </KeyboardAvoidingView>
);

In this scenario, the FlatList is never loaded. When I delete flex:1 from both components, FlatList renders properly but selecting an Input does not make it scroll up
