I understand that the sublist method works similar to slicing, but what are some other ways i can get similar outputs?
For example
List = [1,3,5,7,9]
Python code
ListSliced = List[1:]
Using sublist in dart
ListSliced = List.sublist(1);
Is there a equivalent of List[1:]
in DART??
Code written in dart. List<dynamic>' is not a subtype of type 'bool' branches(tree) { return tree.sublist(1); } isLeaf(tree) { return (!branches(tree)); }
Equivalent code in python. def branches(tree): return tree[1:] def is_leaf(tree): return not branches(tree)
Any ideas on whats causing this error
Full code for the tree program.
bool isTree(tree) { if ((tree is! List) | (tree.length < 1)) { return false; } for (final branch in branches(tree)) { if (!isTree(branch)) { return false; } } return true; } branches(tree) { return tree.sublist(1); } Object label(tree) { return tree[0]; } List tree(rootLabel, [List branches = const []]) { for (final branch in branches) { assert(isTree(branch)); } return ([rootLabel] + branches); } isLeaf(tree) { return (!branches(tree)); } var t = tree('hey', [ tree('hello'), tree('hum', [tree('there'), tree('hey')]) ]);

Answer
Another way is to use skip
For example:
List l = [1,3,5,7,9]; print(l.skip(2)); //prints (5,7,9)
