No named parameter with the name 'nullOk' error in flutter
After lots of effort, I found a successful answer to remove this error.
If you have added SVG dependency in pubspec.yaml so you have replaced this to
nullOk parameters have been removed as part of null safety post-migration. You can read more on the corresponding design doc and its upcoming migration guide.
TL;DR you can try to use
.maybeOf(context) instead of
.of(context, nullOk: true);
You may have to update your dependencies to make it work.
