Create nested values and any intermediaries using list notation
['a','b',c']OR dot notation"a.b.c".
This is a Dart copy of the js project set-value by Jon Schlinkert.
Please consider following either (or both) projects and starring the projects to show your ❤️ and support.
Also, feel free to make pull requests, open issues, or just let me know if I've messed up. The goal is to keep this project in-line with the original as far as possible.
Lastly, please consider following the project author Ferdinand Steenkamp.
Install with pub.dev, add this to your pubspec.yaml:
dependencies:
set_value:
Then run flutter pub get.
Import the package:
import 'package:set_value/set_value.dart';
void main() {
var mock = <String, dynamic>{}
var setValue = SetValue();
// set a value in a map
mock = setValue.setDot(mock, 'a.b.c', 'Value', splitAt = '.', escapeWith = '\\');
// unset value in a map
mock = setValue.unsetDot(mock, 'a.b.c');
//get value in a map, returns null if it doesn't exists
print(setValue.getDot(mock, 'a.b.c'));
}
Notes:
Escaping: You can escape a split character using \\, alternatively, you can add your own escape character using the optional escapeWith option.
Dot Notation: The dot notation oviously uses...dots. Alternatively, you can add your own dot character using the optional splitAt option.
void main() {
var mock = <String, dynamic>{}
var setValue = SetValue();
// set a value in a map
mock = setValue.set(mock, ['a', 'b', 'c'], 'Value');
// unset value in a map
mock = setValue.unset(mock, ['a', 'b', 'c']);
//get value in a map, returns null if it doesn't exists
print(setValue.get(mock, ['a','b','c']));
}
Pull requests and issues always welcome. There is a lot more information on this project at the original set-value.
