Using the Linter

DO prefer declaring for-each loop variables as final if they are not reassigned later in the code.

Declaring for-each loop variables as final when possible is a good practice because it helps avoid accidental reassignments and allows the compiler to do optimizations.

BAD:

for (var element in elements) { // LINT
  print('Element: $element');
}

GOOD:

for (final element in elements) {
  print('Element: $element');
}

GOOD:

for (var element in elements) {
  element = element + element;
  print('Element: $element');
}
