Function? equals

A Function to use check whether the value of an observable has changed.

Must be a top-level or static Function that takes two arguments and returns a bool. The arguments are the old value and the new value of the observable. If the function returns true, a reaction will be triggered. If the function returns false, no reaction will be triggered. If no function is provided, the default behavior is to only trigger if : oldValue != newValue.

Implementation

final Function? equals;
