How to set up strong-mode Dart Analyzer in Webstorm?

Issue

In my Dart yaml file I have

analyzer:
  strong-mode: true

but it doesn’t do anything. I also added the analyzer:

dependencies:
   analyzer: any
   browser: ^0.10.0
   polymer: ^1.0.0-rc.16
   polymer_elements: ^1.0.0-rc.8

I’m missing something (brain I reckon). What is it please?

Thanks

Steve

Solution

Add a file analysis_options.yaml (.analysis_options old) in the directory where your pubspec.yaml is.

add

analyzer:
  strong-mode: true

or if you also want to disable implicit-casts and/or implicit-dynamic

analyzer:
  strong-mode:
    implicit-casts: false
    implicit-dynamic: false

You can also enable additional linter rules

linter:
  rules:
    - always_declare_return_types

For all supported linter rules see http://dart-lang.github.io/linter/lints/ and Suppress hint about use of protected member
