Tx<T> class

Tx<T> is a Trackable variable that can used to set callbacks which can be called before and after changes are made to the variable.

T value

Is the actual value of the variable. It is split into a Getter and a Setter.

void Function(T)? beforeChange

Is called just before a change of value happens to the variable. This can be null, in which case, there will be no callback before change in value.

void Function(T)? afterChange

Is called immediately after a change of value of the variable happens. This can be null, in which case, there will be no callback after change in value.
