getAsInt method
Retrieves the element of key
of type int from Map.
If Map does not have an element of key
or the type does not match int, orElse
is returned.
Implementation
int getAsInt(K key, [int orElse = 0]) {
assert(key != null, "The key is empty.");
if (!containsKey(key) || this[key] is! num?) {
return orElse;
}
return (this[key] as num?)?.toInt() ?? orElse;
}
