Properties

apiContract → ChartApiContract?

Available on Widget, provided by the ChartWidgetApiContractExtension extension

no setter
autoNormalizePayload → bool
Normalize payload before validate/parse.
final
catchRenderErrors → bool
If true, config resolution/build errors render a fallback instead of bubbling through Flutter's widget error path.
final
config → BaseChartConfig?
Chart configuration object (optional if using jsonConfig)
final
diagnosticFallbackOptions → TenunDiagnosticFallbackOptions
Optional presentation options for the built-in diagnostic fallback widgets.
final
dropUnsupportedSampling → bool
If true, unsupported chart types are normalized to regular mode and sampling is disabled during auto-normalization.
final
hashCode → int
The hash code for this object.
no setterinherited
height → double?
Optional height constraint
final
jsonConfig → Map<String, dynamic>?
JSON configuration (optional if using config)
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
normalizationOptions → PayloadNormalizationOptions?
Optional reusable normalization policy. When provided, it takes precedence over individual normalization parameters above.
final
normalizeDefaultMode → ChartDataMode
Default mode used by auto-normalization fallback.
final
normalizeDefaultThreshold → int?
Optional threshold override used by auto-normalization fallback.
final
onPayloadNormalizationResult → void Function(PayloadNormalizationResult result)?
Optional callback to inspect the exact JSON payload used for rendering.
final
onRenderError → ChartRenderErrorHandler?
Optional callback for render-time config/build failures.
final
onRuntimeDiagnostics → void Function(ChartRuntimeDiagnostics diagnostics)?
Optional callback for lightweight runtime/build diagnostics.
final
onValidationResult → void Function(ValidationResult result)?
Optional callback to receive validation result.
final
padding → EdgeInsetsGeometry?
Optional padding
final
renderErrorBuilder → ChartRenderErrorBuilder?
Optional custom builder for render-time config/build failures.
final
runtimePerformancePolicy → ChartRuntimePerformancePolicy
Optional thresholds for runtime performance recommendations.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sanitizeTradingPayload → bool
If true, auto-normalization also repairs trading payloads by extracting numeric price rows and clamping invalid trading parameters.
final
strictValidation → bool
If true, invalid payload/config shows an error widget instead of rendering.
final
validatePayload → bool
Run payload/config validation before rendering.
final
validationErrorBuilder → Widget Function(BuildContext context, ValidationResult result)?
Optional custom builder for strict validation failure UI.
final
validationReportMaxIssues → int
Maximum validation issues shown by the default strict-validation fallback.
final
width → double?
Optional width constraint
final
