Description:
scoper
Scoper #
A minimal state management solution for Flutter. #
How to use: #
Create custom ExampleScope by extending Scope.
Use notifiyBuilders() to trigger rebuild of ScopeBuilder<ExampleScope>.
Use notifiyExecutors() to trigger execution of ScopeExecutor<ExampleScope>.
class CounterScope extends Scope {
int _counter = 0;
int _divider = 7;
increment() {
_counter++;
notifiyBuilders();
if(_counter % _divider == 0) {
notifiyExecutors();
}
}
get counter => _counter;
get divider => _divider;
}

Register your scopes by passing them to a ScopeRegistrant at the root of the widget-tree.
ScopeRegistrant(
scopes: [
CounterScope(),
ExampleScope(),
],
child: Container(
child: (...)
),
)
copied to clipboard
Use a ScopeBuilder<ExampleScope> to build widgets depending on the given scope.
ScopeBuilder<CounterScope>(
builder: (context, scope) {
return Text(scope.counter.toString());
},
),
copied to clipboard
Use a ScopeExecutor<ExampleScope> to execute certain logic depending on the given scope.
ScopeExecutor<CounterScope>(
executor: (context, scope) {
final message = "This number is divisible by " + scope.divider.toString();
final snackbar = SnackBar(content: Text(message));
ScaffoldMessenger.of(context).showSnackBar(snackbar);
},
child: Container(
child: (...)
),
)

Use get<ExampleScope> to get a scope from context and call it's methods (for example in onPressed).
context.get<CounterScope>().increment(),
