Want to update value for TextField using StreamBuilder? We have just used SharedPreferences instead of sqflite for the below example.Same thing can be done with sqflite.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 | class _MyHomePageState extends State<MyHomePage> { MyBloc myBloc = MyBloc(); TextEditingController myController = TextEditingController(); @override void dispose() { myBloc?.close(); myController?.dispose(); super.dispose(); } @override void initState() { super.initState(); AppPreferences.setString("data", "this is my data"); AppPreferences.getString("data").then((value){ myBloc.dataChanged(value); }); } @override Widget build(BuildContext context) { return Scaffold( body: Center( child: StreamBuilder( stream: myBloc.data, builder: (context,snapshot){ debugPrint(snapshot.data); myController.value = myController.value.copyWith(text: myBloc.dataValue); return TextFormField( controller: myController, onChanged: (value){ myBloc.dataChanged(value); }, ); }, ), ), ); } } |
