chartSwitchCompatibilityForJson function

ChartSwitchCompatibility chartSwitchCompatibilityForJson(Map<String, dynamic> source, { required ChartType targetType, bool registeredOnly = true, })

Checks whether targetType can safely consume source without throwing.

isCompatible means the target accepts the inferred source data shape directly. forceConversionAvailable means Tenun can perform a supported cross-shape conversion when force: true is used with switchChartTypeForSeriesShape.

  final targetShape = targetSeriesDataShape(targetType);
  final targetCapabilities = chartCapabilitiesForType(targetType);
  final targetRegistered =
      !registeredOnly || ChartRegistry.isRegistered(targetType);
  final compatibleTypes = compatibleChartTypesForShape(
    sourceShape,
    registeredOnly: registeredOnly,
  );
  final isCompatible = targetRegistered && compatibleTypes.contains(targetType);
  final forceConversionAvailable =
      targetRegistered &&
      !isCompatible &&
      _hasSupportedForceConversion(source, targetType);
