2. Install it
You can install packages from the command line:

3. Import it
Now in your Dart code, you can use:
import 'package:liquid_pull_to_refresh/liquid_pull_to_refresh.dart';
Usage
For adding this custom refresh indicator in your flutter app, you have to simply wrap ListView or GridView inside LiquidPullToRefresh. Also you have provide the value of onRefresh parameter which is a refresh callback.
Note - LiquidPullToRefresh can only be used with a vertical scroll view.
For example:
LiquidPullToRefresh(
key: _refreshIndicatorKey, // key if you want to add
onRefresh: _handleRefresh, // refresh callback
child: ListView(), // scroll view
);
If you do not want the opacity transition of child then set showChildOpacityTransition: false. Preview regarding the both form of this widget is follows :-
showChildOpacityTransition: true | showChildOpacityTransition: false |
