extract method

Future<CoverageExtractionResult> extract({ required Directory packageDirectory, required bool showTestOutput, List<String>? includeRegexes, List<String>? excludeRegexes, bool? ignoreBarrelFiles, })

Runs the given package tests with the processRunner, parses the coverage output with the hitmapReader and creates a CoverageReport with the coverageReportFactory with the resulting hitmaps. Return a CoverageExtractionResult containing the coverage report and the status of the tests executed as a TestResultStatus. If the showTestOutput flag is true, the tests outputs will be shows in the console
