Constant Summary collapse

ALL_IMPORTS_TEST_FILE =

Although this file is autogenerated, we should not call it “.g.dart”, because it is common for coverage configuration to exclude such files. Note that it’s also common to configure Dart analyser to exclude these files from checks; this won’t match, and we have to use ignore_for_file for all known lint rules that we might be breaking.
