Test run failed with error.

Hi everyone, I'm facing an issue while running the test, you can see below the error I got in terminal while running the
"dart --pause-isolates-on-exit --enable_asserts --enable-vm-service
test/.test_coverage.dart"
command. The .test_coverage.dart file is generated in test folder but couldn't run the test I,e step 2.
