The dart2js (pre)compiled version of my app is throwing this error:

Uncaught Error: NullError: Cannot call "call$1" on null main_window.dart.precompiled.js:103735
Stack Trace:
TypeError: Cannot call method 'call$1' of undefined
    at EditableLabel.displayFilter$1 (chrome-extension://ogbfcncmbpliojmfiagabpcojeoonkej/main_window.dart.precompiled.js:116979:33)
    at EditableLabel.set$text (chrome-extension://ogbfcncmbpliojmfiagabpcojeoonkej/main_window.dart.precompiled.js:117000:59)

The generated code in the call stack looks like:

displayFilter$1: function($receiver, arg0) {
      return this.displayFilter.call$1(arg0);
    },

displayText = receiver.displayFilter != null ? this.displayFilter$1(receiver, t) : t;

I think the problem is that it is using 'this' instead of 'receiver' above?

The original dart code looks like:

  if (displayFilter != null) {
    displayText = displayFilter(t);
  }

Where 'displayFilter' is an instance field of a custom element:

Function displayFilter;

thanks,

If I hack the generated javascript function to be the following (use $receiver instead of this), then it works:

displayFilter$1: function($receiver, arg0) {
  return $receiver.displayFilter.call$1(arg0);
},
