What steps will reproduce the problem?
I think it has to do when making multiple calls to window.requestLayoutFrame under certain circumstances. I must confess I can reproduce this in my own code, but have been unable to isolate it to a simple example.
What is the expected output? What do you see instead?
Everything renders fine on the browser, but the javascript console displays this message:
Uncaught TypeError: Cannot read property 'length' of null
_completeMeasurementFutures
_maybeScheduleMeasurementFrame.$globals._firstMeasurementRequest
wrapped
Digging in to the javascript itself I see that it's happening here when $globals._pendingRequests returns null in this function:
function _completeMeasurementFutures() {
if ($eq($globals._nextMeasurementFrameScheduled, false)) {
return;
}
$globals._nextMeasurementFrameScheduled = false;
var $list = $globals._pendingRequests;
for (var $i = 0;$i < $list.length; $i++) {
//LUCA_UI_Demo.dart.app.js:3983 Uncaught TypeError: Cannot read //property 'length' of null
var request = $list.$index($i);
try {
request.value = request.computeValue();
} catch (e) {
e = _toDartException(e);
request.value = e;
request.exception = true;
}
}
What version of the product are you using? On what operating system?
