LiveTextButton class abstract
A TextButton widget with its properties controlled by ValueCell's.
The constructor takes mostly same arguments as the unnamed constructor of TextButton,
but as ValueCell's. Instead of taking a callback function
for onPressed
, the constructor accepts an ActionCell that is triggered when
the button is pressed.
bool MetaCells are accepted for onHover
and onFocusChange
. This allows
the hover and focus state of the widget to be observed by observing the MetaCells
passed to the constructor.
