# This file configures the analyzer, which statically analyzes Dart code to |
|
# check for errors, warnings, and lints. |
|
# |
|
# 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, |
|
# packages, and plugins designed to encourage good coding practices. |
