This is the code in my
component.html (Angular Dart template):
<div *ngIf="selectedOffer!=null && !selectedOffer.isBotenOffer">...</div>
This is the exception I get:
EXCEPTION: NoSuchMethodError: The getter ‘isBotenOffer’ was called on
null. Receiver: null Tried calling: isBotenOffer
selectedOffer my be
null sometimes. But why is the second statement evaluated if the first is false? And how can I around this best?
Angular will write this into the generated template file:
_NgIf_0_5.ngIf = ((ctx.selectedOffer != null) && !ctx.selectedOffer.isBotenOffer);
So it shouldn’t evaluate
null. However, you may be hitting a bug that was just fixed in dart2js: https://github.com/dart-lang/sdk/commit/fe7baee84828e109a49920c2572f3917e5ff8ca5
You might hit this issue if you are setting
selectedOffer in your component’s constructor, but doing an early return in the constructor.
