LiveElevatedButton class

An ElevatedButton widget with its properties controlled by ValueCell's.

The constructor takes mostly same arguments as the unnamed constructor of ElevatedButton, but as ValueCell's. This binds each property value to the ValueCell given in the constructor. If the cell value is changed, the value of the corresponding property to which it is bound is automatically updated to reflect the value of the cell.

Instead of taking callback functions for onPressed and onLongPress, the constructor accepts MetaCell's that are set to ActionCells which are triggered when the button is pressed and long pressed respectively. Similarly, bool MetaCells are accepted for onHover and onFocusChange.
