OrbitBuilder<T extends OrbitStore> class

Rebuilds builder whenever store T changes.

No provider setup, no wrapping your app in anything for the default case — store is only used the very first time this store is requested anywhere in the app; every widget asking for T afterwards shares one instance. If this widget sits inside an OrbitScope<T>, it automatically uses that scoped instance instead — no change needed here.

OrbitBuilder<CounterStore>(
  store: () => CounterStore(),
  builder: (context, store, child) => Text('${store.count}'),
)

If part of your subtree doesn't depend on the store, pass it as child instead of building it inline — like AnimatedBuilder, it's built once and passed through on every rebuild instead of being reconstructed each time the store changes.

Properties

builder → Widget Function(BuildContext context, T store, Widget? child)
final
child → Widget?
A subtree that doesn't depend on the store; built once and reused.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
store → T Function()
Factory used only the first time this store type is requested globally. Ignored if an ancestor OrbitScope<T> provides one.
