javaScript property

String? javaScript
final

JavaScript-based function code to be called.

If a dart-based function is also defined, this will be called in parallel.

The code runs inside function(...args){...}, so it can use this, args, and event as a shorthand for args[0]:

HighchartsCallback(null, 'event.preventDefault();')

Call event.preventDefault() here rather than from a dart-based callback. A dart-based callback receives only a JSON snapshot of the event, delivered after the JavaScript function has already returned.

Implementation

final String? javaScript;
