You can try:
void main(){
List<String> params = ['A','B','C'];
final out = params.map((e) => "['$e']").join();
print(out);
}
Prints:
['A']['B']['C']

@SK- It's hard to tell within the comment section. Please consider asking as a new question on Stack Oveflow.
you can do this
List<String> params = ['A','B','C'];
List newParams = [];
for(var item in params){
newParams.add([item]);
}
String stringParams = newParams.toString();
String noBracketParams = stringParams.substring( 1, stringParams.length - 1 );
String noCommasParams = noBracketParams.replaceAll(',', '');
print(noCommasParams);

- I'm not sure what you're trying to do, but it can be achieved like this
List<String> params = ['A', 'B', 'C'];
List.generate(
params.length, (index) => params[index] = '''['${params[index]}']''');
var str = '';
params.forEach((item) => str += item);
print(str);
