initState method

@mustCallSuper void initState()

The framework will call this method exactly once. Only when the StateX object is first created.

Implementation

@mustCallSuper
void initState() {
  /// Override this method to perform initialization that depends on the
  /// location at which this object was inserted into the tree.
  /// (i.e. Subscribe to another object it depends on during [initState],
  /// unsubscribe object and subscribe to a new object when it changes in
  /// [didUpdateWidget], and then unsubscribe from the object in [dispose].
}
