0.2.0 - Mar 23, 2022

[hoc081098]

https://pub.dev/packages/rxdart_ext/versions/0.2.0

• utils:

  • Add DisposableMixin. This mixin adds an easy option to dispose Streams without having to store
    a StreamSubscription variable. (Thanks to Jop Middelkamp).
  • Add Equality typedef.

• state_stream:

  • Rename StateStream.defaultEquals to StateStream.defaultEquality.
  • Add StateStream selectors (SelectorsStateStreamExtensions): StateStream.select, StateStream.select2
    to StateStream.select9
    and StateStream.selectMany.
    • Select a sub state slice from state stream. Inspirited
      by NgRx memoized selector
    • Selectors can compute derived data, to store the minimal possible state.
    • Selectors are efficient. A selector is not recomputed unless one of its arguments changes.
    • When using the select, select2 to select9, selectMany functions, keeps track of the latest arguments
      in which your selector function was invoked. Because selectors are pure functions, the last result can be
      returned when the arguments match without re-invoking your selector function. This can provide performance
      benefits, particularly with selectors that perform expensive computation. This practice is known as
      memoization.
