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>[];
// LINT: Calling 'reduce' on an empty collection will throw an exception.
// Try checking if this collection is not empty first.
final sum = list.reduce((a, b) => a + b);
}
✅ Good:
void fn() {
final list = <int>[];
final sum = list.isEmpty ? null : list.reduce((a, b) => a + b); // Correct, has a length check first
// OR
if (list.isNotEmpty) {
final sum = list.reduce((a, b) => a + b);
}
}
