I have a string like this:
'var key1 = "abcd"; var key2 ="xyz";'
and I want to convert this into the map or JSON, in Dart, like this:
{
'key1': 'abcd',
'key2': 'xyz'
}
Is there a way I can convert the J/S file as a string to a Dart map?

To generate a Map form your string. You can use the help of regular expressions (online demo).
The following code captures two groups that are within the () and creates a Map out of them:
void main() {
final s = 'var key1 = "abcd"; var key2 ="xyz"';
final reg = RegExp(r'var (.*?)=\s?"(.*?)"');
final myMap = Map.fromEntries(
reg.allMatches(s).map((m) => MapEntry(m.group(1), m.group(2))));
print(myMap);
}
Output:
{key1 : abcd, key2 : xyz}
