Flutter-intellij: Plugin does not use .analysis_options_user file

[raju-bitter]

The Flutter plugin in IntelliJ does not use the analyzer settings in
https://github.com/flutter/flutter/blob/master/.analysis_options_user

When running flutter analyze from the command line inside a Flutter project created with the IntelliJ plugin, settings from .analysis_options_user file are used.

When using a project specific .analysis_options file, IntelliJ plugin applies those settings.

Steps to Reproduce

1. Create a new Flutter project with IntelliJ

2. Add the following lines of code to lib/main.dart
   ```
   var list = ["hello", "world"];
   List listOfInts = list;

3. **Dart Analysis in IntelliJ does not show any warnings.**

4. **In the project folder  run `flutter analyze`.**
Since strong mode is enabled in `.analysis_options_user`, the following warning is displayed:
> flutter analyze
> Running 'flutter packages get' in learning-flutter... 432ms
> Analyzing 2 files...
> [warning] A value of type 'List<String>' can't be assigned to a variable of type 'List<int>'. (lib/HelloWorld.dart, line 2, col 24)
> (Ran in 5.8s)

5. **Create an `.analysis_options` file in the main project folder with the following content:**

analyzer:
strong-mode: true
```

1. Dart Analysis panel will show the same warning
   > ERROR: A value of type 'List' can't be assigned to a variable of type 'List'. ([learning_flutter] lib/main.dart:4)

@danrubel any idea on this one?

[danrubel]

Addressing issues like this is part of my long arc of work to cleanup the differences between analysis server, dartanalyzer, and flutter analyze.

[mit-mit]

Great. Is there a master/meta bug we can link the individual issues like this one to?

@danrubel : is this issue better tracked elsewhere?

[danrubel]

This should be fixed as of https://github.com/flutter/flutter/commit/52245e5082d70e089d6b9460a681849000de2340
to use the analysis options in package:flutter/analysis_options_user.yaml.

Please re-open if this is not the case.
