debugGetOpenHandleStackTraces method
If asserts are enabled, returns the StackTraces of each open handle from clone, in creation order.
If asserts are disabled, this method always returns null.
Implementation
List<StackTrace>? debugGetOpenHandleStackTraces() {
List<StackTrace>? stacks;
assert(() {
stacks = _image._handles.map((Image handle) => handle._debugStack!).toList();
return true;
}());
return stacks;
}
