Plugin does not use .analysis_options_user file

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<int> listOfInts = list;

1. Dart Analysis in IntelliJ does not show any warnings.

2. 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)

1. 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<String>’ can’t be assigned to a variable of type ‘List<int>’. ([learning_flutter] lib/main.dart:4)

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.

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