every method
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)) => value.every(test);
