every method
- bool test(
- E element
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
.
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
bool every(bool test(E element)) { for (E element in this) { if (!test(element)) return false; } return true; }
