Implementation

@override
Future<bool> load() {
  return _loadController.load(() async {
    var jsFullPath = minified ? JS_PATH_MIN : JS_PATH;
    var okJS = await AMDJS.require('chartjs',
        jsFullPath: jsFullPath, globalJSVariableName: 'Chart');
    var okWrapper = await AMDJS.require(JS_WRAPPER_GLOBAL_NAME,
        jsFullPath: ENGINE_WRAPPER_PATH,
        globalJSVariableName: JS_WRAPPER_GLOBAL_NAME);

    _jsWrapper = context[JS_WRAPPER_GLOBAL_NAME] as JsObject?;

    _allowInterop();

    return okJS && okWrapper;
  });
}
