The return types of the following methods are changed to `ExpressionTypeAnalysisResult`: - `NullShortingMixin.finishNullShorting` (previously returned `SharedTypeView`). - `NullShortingMixin.handleNullShortingStep` (previously returned `void`). - `TypeAnalysisNullShortingInterface.finishNullShorting` (previously returned `SharedTypeView`). - `TypeAnalyzer.analyzeExpression` (previously returned `SharedTypeView`). With one exception, these methods previously returned a `SharedTypeView` representing the expression's static type. (The exception was `NullShortingMixin.handleNullShortingStep`, which previously returned `void`). This paves the way for allowing these methods to return additional information beyond the static type of the expression, such as flow analysis results and tree rewrite information. (This information is currently carried around in auxiliary data structures, which leads to bookkeeping headaches and increases the risk of bugs.)

FE/analyzer shared code
This package contains logic that is shared between the front_end and analyzer packages. It is intended solely to facilitate development of the Dart SDK, and is not intended for use by end users. In particular, this package has no public API, so no guarantee is made of compatibility between one version of the package and the next.
End users should consider using the analyzer package to analyze Dart source code.
