RadioSelector<T extends Enum> class
A radio selector widget that allows the user to select a value from a list of enum values.
The widget is a stateful widget that requires an initialValue to set the initial value of the selector, a list of enumValues to set the values that the user can select, an onChanged callback to be called when the user selects a value, a getLabel function to get the label of a value, and an errorText to display an error message.
The widget displays a list of radio buttons that the user can select. The radio buttons are displayed in a row and the labels of the values are displayed next to the radio buttons. The selected value is highlighted with a different color. If an error message is provided, it is displayed below the radio buttons.
