K, V>.from constructor Null safety
- Map other
Creates a LinkedHashMap with the same keys and values as
The keys must all be instances of
K and the values of
other map itself can have any type, unlike for Map.of,
and the key and value types are checked (and can fail) at run-time.
Prefer using Map.of when possible, and only use
to create a new map with more precise types than the original,
and when it's known that all the keys and values have those
more precise types.
LinkedHashMap requires the keys to implement compatible
It iterates in key insertion order.
