FunctionToJSExportedDartFunction

extension FunctionToJSExportedDartFunction on Function

Conversions from Function to JSExportedDartFunction.

Properties

toJS extension no setter

JSExportedDartFunction get toJS

A callable JavaScript function that wraps this Function.

If the static type of the Function could not be determined or if the static type uses types that are disallowed, the call will fail to compile. See https://dart.dev/interop/js-interop/js-types#requirements-on-external-declarations-and-function-tojs for more details on what types are allowed.

The max number of arguments that are passed to this Function from the wrapper JavaScript function is determined by this Function's static type. Any extra arguments passed to the JavaScript function after the max number of arguments are discarded like they are with regular JavaScript functions.

Calling this on the same Function again will always result in a new JavaScript function.

Available on Function, provided by the FunctionToJSExportedDartFunction extension

Implementation

external JSExportedDartFunction get toJS;

toJSCaptureThis extension no setter

JSExportedDartFunction get toJSCaptureThis

A callable JavaScript function that wraps this Function and captures the this value when called.

Identical to toJS, except the resulting JSExportedDartFunction will pass this from JavaScript as the first argument to the converted Function. Any Function that is converted with this member should take in an extra parameter at the beginning of the parameter list to handle this.

Available on Function, provided by the FunctionToJSExportedDartFunction extension

Implementation

@Since('3.6')
external JSExportedDartFunction get toJSCaptureThis;
