Getting error at compile time

[kamleshwebtech]

Could you please suggest me what is that issue and how can we solve it?

Below is the error I am getting on console panel of vscode editor:

../../flutter/.pub-cache/hosted/pub.dartlang.org/flutter_datetime_picker-1.5.1/lib/flutter_datetime_picker.dart:311:32: Warning: Operand of null-aware operation '??' has type 'Color' which excludes null.
 - 'Color' is from 'dart:ui'.
                  color: theme.backgroundColor ?? Colors.white,

Please suggest. Thanks.

Same error, but still compiles just fine (using unsound null-safety)

I get the same problem.Did you solve it

I Solved it by editing the line no 311 of the flutter_datetime_picker.dart. You can find this file in External Librariers->DartPackages

Thanks.
color: theme.backgroundColor ?? Colors.white -> color: theme.backgroundColor

It's just a warning, so no need to worry. It was fixed with this PR #236 but apparently didn't make it into the latest deployment.

If you want, pulling from master instead of pub.dev should solve it until a new version is deployed.
