I have a few variables that I am not using/referring to anywhere in the project so I am getting a unused_local_variable warning.

Currently I am using

// ignore_for_file: unused_local_variable

to ignore those warning for that file but I have many files and I don't want to write the same in each one of them. So, how can I suppress this warning for the entire project?

Adding this to analysis_options.yaml file didn't work:

linter:
  rules:
     unused_local_variable: false

CodePudding user response：

unused_local_variables isn't a lint rule (it's not listed by https://dart.dev/tools/linter-rules or in https://github.com/dart-lang/linter/blob/main/example/all.yaml), so disabling it under linter: rules: will have no effect.

unused_local_variables instead is an analyzer code. Per https://dart.dev/guides/language/analysis-options#ignoring-rules, you can edit your analysis_options.yaml file and add:

analyzer:
  errors:
    unused_local_variable: ignore

That said, really you should just get rid of your unused local variables.
