In Python, strings and lists are two fundamental data structures often used together in various applications. Converting a Python string to a list is a common operation that can be useful in many scenarios, such
Each element in a string is converted into an int usingint.parse Finally, returns the elements into a list usingtoList() voidmain() {List<String> strs=<String>["11","12","5"];print(strs.runtimeType);List<int> numbers=strs.map(int.parse).toList();print(numbers.runtimeType);prin...
