Try it

A sample app is available to let you try all the features ! :)

Warning

If you want to use a SearchBarController in order to do some sorts or filters, PLEASE put your instance of SearchBarController in a StateFullWidget.

If not, it will not work properly.

If you don't use an instance of SearchBarController, you can keep everything in a StateLessWidget !
