every method
inherited
Checks whether every element of this iterable satisfies test.
Checks every element in iteration order, and returns false if
any of them make test return false, otherwise returns true.
Returns true if the iterable is empty.
Example:
final planetsByMass = <double, String>{0.06: 'Mercury', 0.81: 'Venus',
0.11: 'Mars'};
// Checks whether all keys are smaller than 1.
final every = planetsByMass.keys.every((key) => key < 1.0); // true
Implementation
@override
bool every(final bool Function(T element) test) {
for (final T item in this) {
if (!test(item)) {
return false;
}
}
return true;
}
