Dart Analysis Tool Window
The tool window is available only when the Dart plugin is installed and enabled. The plugin is activated by default. If the plugin is disabled, enable it on the Plugins page as described in Managing plugins.
WebStorm integrates with the Dart Analyzer tool that performs static analysis of your Dart source code. All inconsistencies and potential problems are reported in the Dart Analysis tool window with the possibility to navigate to the fragment of the source code where the problem was detected.
All the problem reports are displayed in a table which consists of two columns, Description and Location, and a summary below.
The Description column shows the message itself, which can be an error message, a warning, or a hint.
The Location column shows the following data:
The name of the Dart package in which the problem arose. The Dart package name corresponds to the
project namefrom pubspec.yaml.
The relative from the Dart package root to the file where the problem arose.
The line number where the problem arose.
The Summary area below the table shows the number of detected errors, warnings, or hints and the filter status.
Grouping and Sorting
The messages in the Dart Analysis tool window can be grouped and sorted. By default, the messages are primarily sorted by their severity, that is, the error messages are shown at the top of the list, then come warnings, and finally hints are displayed. In each severity group, messages are grouped by the Dart package name, which is super handy for projects with multiple pubspec.yaml files. In each package group, the messages are grouped by their file paths. Finally, in each file group, the problems are sorted by the line number where they occurred.
Click the Location column header to switch between the ascending and descending order of the Dart package name + file path sorting. Note that this does not affect the order of severity groups, that is, errors are always shown first. Line numbers are not taken into consideration either, for each particular file problems are always shown in ascending order of line numbers.
To disable the primary grouping by severity, release the Group by Severity toggle button on the toolbar. After that the severity of a problem is not taken into consideration at all and problem reports are sorted only by their Description or Location (Dart package name + file path). This sorting method guarantees that all the problems for each particular file are grouped together in the table, regardless of their severity.
