LiveTextButton class
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. 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.
