avoid-unsafe-reduce
Warns when the .reduce
collection method is called on a potentially empty collection.
Calling .reduce
on an empty collection will result in a runtime exception.
Example
❌ Bad:
void fn() {
final list = <int>[];
final sum = list.reduce((a, b) => a + b); // LINT
}
✅ Good:
void fn() {
final list = <int>[];
final sum = list.isEmpty ? null : list.reduce((a, b) => a + b);
// OR
if (list.isNotEmpty) {
final sum = list.reduce((a, b) => a + b);
}
}
