Can you please add more information?
flutter doctor -vbuild_runneryou're usingbuild.xxx.yamlfile involvedimyyq-star commentedon Mar 16, 2018
The build package I use is
json_serializable. Runningflutter packages pub run build_runner buildagain today is not an error. I didn't do anything before.I use
build_runner-0.7.11+1.Here is the result of my running: "flutter doctor -v".
Not quite understand what you said: "is build.xxx.yaml file involved"
