Methods
-
fetch(
String url, {dynamic nocache = false, dynamic allowErrorWhenCacheExists = false, Map< String, String> ? headers, String? cacheUrl, String? body, bool usePost = false}) → Stream<T> -
by default, if cached version is available then errors will not be pushed to stream
nocache
skip cached versionallowErrorWhenCacheExists
throw errors even if cache is exists ifcacheUrl
is specified, then content will be cached under it -
get(
String url, {Map< String, String> ? headers, String? body, bool usePost = false}) → Future<T> - just get without caching
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited

parse(
String source) → FutureOr< T> - implement me: returns object parsed from json
-
toString(
) → String -
