Extreme minimalist flutter state framework, inspired by fish-redux from Alibaba

Architecture

See simple state article in the resources section. The widgets that listen to the state and rebuild on a change are generally called builder widgets. We can hide futures behind a ValueNotifier, but can be done with streams as well.

If the UI needs to listen to state that’s in a ValueNotifier, then you should use a ValueListenableBuilder widget. The long name is rather unfortunate because it’s job is quite simple. Just rebuild a little section of the UI with the new value.

• getit: to access the state
• config.dart: it contains all we need in most of the application.
• base.dart: all we need for our state framework :)
• every page is a class that contains effect, reducer and state, and we
• register pages in the app.dart
• so from any component can access other pages state we also can have a global common state
• views access 'page' using getit
• state only function is 'apply' to change for a new copy of the state, that is in the 'value' variable from the
• access to database, API, etc... only in effect.
• effects, reducers and actions only contain functions, but the state is indeed a class, once it's the only part that we need to keep data in the memory. Following this pattern we go for a more functional approach.
• to change the state we have ONLY one function, 'apply', and business logic is concentrated only on reducers.

Graphql

Use the graphqlbin to play. You can point to https://graphql.bitquery.io .

• graphql - dart graphql client

File Structure

• config:
  • boot.dart: all the initalizations needed when the application starts
