I have an error in the in the overlay.dart file when compliling the flutter project

Question

when building my flutter project that was compiling perfectly without any problem before but since yesterday i got that problem ans i did all what i could do by upgrading the packages and the flutter itself, but the problem isn't solved

so if anyone face the same problem or have a solution for this problem i would be very thankful

Answer 1

The reason you get the error is Overlay.of(context) could be null. Nullable object should access its field with ?..

Replace Overlay.of(context).context.findRenderObject() with Overlay.of(context)?.context?.findRenderObject() will do the fix.
