map_history
A Map implementation with history and rollback support for entries, keys and values.
Usage
Here’s a simple usage example:
import 'package:map_history/map_history.dart';
void main() {
var m = MapHistory<int, String>();
m[1] = 'a';
m[2] = 'b';
m[3] = 'c';
var ver3 = m.version;
print('Version: $ver3 >> $m');
m[2] = 'B';
m.remove(3);
var ver5 = m.version;
print('Version: $ver5 >> $m');
print('Rollback to version: $ver3');
m.rollback(ver3);
print('Version: ${m.version} >> $m');
}
Output:
Version: 3 >> {1: a, 2: b, 3: c}
Version: 5 >> {1: a, 2: B}
Rollback to version: 3
Version: 3 >> {1: a, 2: b, 3: c}
