+# This file configures the analyzer, which statically analyzes Dart code to

+# The issues identified by the analyzer are surfaced in the UI of Dart-enabled
+# IDEs (https://dart.dev/tools#ides-and-editors). The analyzer can also be
+# invoked from the command line by running `flutter analyze`.

+# The following line activates a set of recommended lints for Flutter apps,

+  # https://dart-lang.github.io/linter/lints/index.html.

+  # Instead of disabling a lint rule for the entire project in the
