Flutter - How set double value to Bloc? - flutter

Question

In my application there is a field for input of a certain value in double format, but this is not working.
What am I doing wrong?
My Bloc
class BudgetBloc extends BlocBase {
String _documentId;
double _movimentos;
BudgetBloc() {
_movimentosController.listen((value) => _movimentos = value);
}
void setBudget(Budget budget) {
_documentId = budget.documentId();
setMovimentos(budget.movimentos);
}
var _movimentosController = BehaviorSubject<double>();
Stream<double> get outMovimentos => _movimentosController.stream;
void setMovimentos(double value) => _movimentosController.sink.add(value);
bool insertOrUpdate() {
var budget = Budget()
..movimentos = _movimentos;
if (_documentId?.isEmpty ?? true) {
_repository.add(budget);
} else {
_repository.update(_documentId, budget);
}
return true;
}
#override
void dispose() {
_movimentosController.close();
super.dispose();
}
}
My BudgetPage
class BudgetPage extends StatefulWidget {
BudgetPage(this.budget);
final Budget budget;
#override
_BudgetPageState createState() => _BudgetPageState();
}
class _BudgetPageState extends State<BudgetPage> {
TextEditingController _movimentosController;
final _bloc = BudgetBloc();
#override
void initState() {
_movimentosController =
TextEditingController(text: widget.budget.movimentos.toString());
super.initState();
}
#override
void dispose() {
_movimentosController.dispose();
super.dispose();
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Add Movimento"),
),
body: Container(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: ListView(
children: <Widget>[
Container(
child: TextField(
decoration: InputDecoration(labelText: "Movimento"),
controller: _movimentosController,
onChanged: _bloc.setMovimentos,
),
),
Container(
height: 20,
),
RaisedButton(
child: Text("Save"),
onPressed: () {
if (_bloc.insertOrUpdate()) {
Navigator.pop(context);
}
},
)
],
),
),
),
);
}
}
Thanks

Function(double) can't be assigned to the parameter type void Function(String)
The error is telling you that you are providing a String when it expects a double.
I would try passing a double to the BLoC, something like this:
onChanged: (value) => _bloc.setMovimentos(double.parse(value)),
