I need to read simple json file synchronously from assets folder. I have made a function which is doing what I need:
Future<void> init() async {
_charList = jsonDecode(await rootBundle.loadString('assets/ble_db/characteristic_uuids.json'));
_servicesList = jsonDecode(await rootBundle.loadString('assets/ble_db/service_uuids.json'));
}
But the only problem of this aproach is async behaviour. For my program it would be much better if it would be a blocking code which i could call from normal function.
When I am trying to use this approach:
var config = new File('./assets/ble_db/service_uuids.json');
var str = config.readAsStringSync();
I am getting an error
Cannot open file, path = './assets/ble_db/service_uuids.json' (OS Error: No such file or directory, errno = 2)
How could i read file from assets folder synchronously?
pubspec.yaml
:flutter:
assets:
- assets/
- assets/ble_db/
var config = new File('assets/ble_db/service_uuids.json');
