Question: RangeError (RangeError (index): Invalid value: Valid value range is empty: -1)
class Stack<T> { final List<T> _items = []; //_items declared as Private void push(T item) => _items.add(item); T pop() => _items.removeLast(); @override String toString() => _items.toString(); } void main() { final stack = Stack<int>(); stack.push(1); stack.push(2); print(stack.pop()); print(stack.pop()); final names = Stack<String>(); names.push('Adam'); names.push('Rose'); print(stack.pop()); } Print command with the 'stack.pop()' method doesn't print the flutter error name values as it does with the int values, How can I fix this?
