Thumper #

A Thumper is a flutter widget that controls an Iterable.

Buttons allow reset, forward step, and play/pause. A slider controls the thumper's frequency (the iteration speed).

There's no backward step, as the basic Iterator interface doesn't require a reversible state generator.

Example #

The example iterates through a list of fruits.

initial	playing

To try it in chrome, install beta channel flutter then:

# Confirm you have some devices.
flutter devices

# Get the code
git clone git@github.com:monopole/thumper.git
cd thumper

# then either
make demo-chrome
# or
make demo-android

For a more complex Thumper demo see the GolGrid widget.
