locale_sweep library

Classes

ArbAnalyzer: Static analyzer for ARB (Application Resource Bundle) translation files.
ArbIssue: A single issue found during ARB analysis.
ArbReport: Result of an ARB analysis containing all detected issues.
DiffResult: Result of comparing two golden screenshots pixel-by-pixel.
GoldenDiffer: Computes pixel-level diffs between golden screenshots and generates side-by-side comparison images.
OverflowDetector: Intercepts FlutterError.onError to capture RenderFlex overflow errors.
OverflowError: A captured RenderFlex overflow error with optional pixel count.
ParsedReport
ReportGenerator: Generates Markdown and JSON reports from sweep results.
SweepConfig: Configuration for a sweep run, loadable from locale_sweep.yaml.
SweepGoldenComparator: A golden file comparator that computes pixel diffs and applies tolerance.
SweepResult: The result of running a single sweep variant.
SweepRunSummary: Aggregates SweepResults with summary statistics.
SweepVariant: A single combination of locale, text scale, viewport, and brightness to test.
ViewportPreset: A named viewport size used to simulate layout dimensions in tests.

sweepResultsDir → const String: Default directory where sweep results are written for CLI consumption.

sweepResults → List<SweepResult>: Returns all results recorded by sweepTest in this test isolate.
no setter

clearSweepResults() → void: Clears all recorded sweep results.
discoverPackages(String root, {String testDir = 'test/sweep'}) → List<String>
loadResults(SweepConfig cfg, {String resultsPath = '.locale_sweep/results'}) → ParsedReport?
mergeResults(List<SweepResult> results) → ParsedReport
parseFlowFromName(String testName) → String
parseLocale(String code) → Locale: Parses a BCP-47 locale string into a Locale.
parseMachineOutput(String output, SweepConfig cfg) → ParsedReport
parseVariantFromName(String testName, SweepConfig cfg) → SweepVariant
shouldFail(ParsedReport report, Set<String> failOn) → bool
sweepTest(String flowName, {required Widget builder(), SweepBody? body, SweepVariantBody? variantBody, SweepConfig? config, List<String>? locales, List<double>? textScales, List<ViewportPreset>? viewports, bool? darkMode, ThemeData? lightTheme, ThemeData? darkTheme, String? arbDir, String? baseLocale, bool captureScreenshots = true, String screenshotDir = '.locale_sweep/screenshots', bool skip(SweepVariant variant)?, double? tolerance, String diffOutputDir = '.locale_sweep/diffs', Future<void> setUp()?, List<LocalizationsDelegate>? localizationsDelegates}) → void: Generates locales × textScales × viewports (× brightness) test cases for flowName.

SweepBody = Future<void> Function(WidgetTester tester): Callback for interactions to run after the widget is pumped.
SweepVariantBody = Future<void> Function(WidgetTester tester, SweepVariant variant): Callback that also receives the current SweepVariant for locale-aware interactions.
