dart:js_util library

Utility methods to efficiently manipulate typed JSInterop objects in cases where the name to call is not known at runtime. You should only use these methods when the same effect cannot be achieved with @JS annotations. These methods would be extension methods on JSObject if Dart supported extension methods.

Functions

callConstructor(Function constr, List arguments) → dynamic

callMethod(dynamic o, String method, List args) → dynamic

getProperty(dynamic o, dynamic name) → dynamic

hasProperty(dynamic o, dynamic name) → bool

instanceof(dynamic o, Function type) → bool

jsify(dynamic object) → dynamic

WARNING: performance of this method is much worse than other util methods in this library. Only use this method as a last resort. [...]

newObject() → dynamic

setProperty(dynamic o, dynamic name, dynamic value) → dynamic
