build abstract method
Initialize a Notifier.
It is safe to use Ref.watch
or Ref.listen
inside this method.
If a dependency of this Notifier (when using Ref.watch
) changes,
then build will be re-executed. On the other hand, the Notifier
will not be recreated. Its instance will be preserved between
executions of build.
If this method throws, reading this provider will rethrow the error.
