TypeChecker.fromUrl constructor
const
TypeChecker.fromUrl(
- dynamic url
Create a new TypeChecker backed by a library url
.
Example of referring to a LinkedHashMap
from dart:collection
:
const linkedHashMap = const TypeChecker.fromUrl(
'dart:collection#LinkedHashMap',
);
NOTE: This is considered a more brittle way of determining the type
because it relies on knowing the absolute path (i.e. after resolved
export
directives). You should ideally only use fromUrl
when you know
the full path (likely you own/control the package) or it is in a stable
package like in the dart:
SDK.
Implementation
const factory TypeChecker.fromUrl(dynamic url) = _UriTypeChecker;
