Answer 1

You can use the replaceAll method.
It would look like String out = firstInput.replaceAll(".","");

Answer 2

You can also use replaceAllwith RE as shown below

void main(){
  final myString = '1.3.4.6.6';
  String withoutDots = myString.replaceAll(RegExp('\\.'), ''); "Here \\ is used to as esc char"
  print(withoutDots); // prints 13466
