ChartRegistry class

Global registry of chart types.

This is the single place that maps chart type strings → config factories. The monolithic getChartConfig switch in helper.dart is replaced by calls to ChartRegistry.resolve.

Static Methods

clear() → void: Clear all registrations (use in tests only).
isRegistered(ChartType type) → bool: True if type has been registered.
isRegisteredString(String s) → bool: True if type string s has been registered.
register(ChartRegistration reg) → void: Register a single chart type.
registerAll(Iterable<ChartRegistration> registrations) → void: Register multiple chart types at once.
registrationForString(String s) → ChartRegistration?: Registration metadata for type string s, including aliases.
registrationForType(ChartType type) → ChartRegistration?: Registration metadata for type, or null when it is not registered.
resolve(Map<String, dynamic> json) → BaseChartConfig: Resolve a BaseChartConfig from a JSON map.
resolveByType(ChartType type, Map<String, dynamic> json) → BaseChartConfig: Resolve by ChartType enum (convenience — avoids string lookup).
restore(ChartRegistrySnapshot snapshot) → void: Restores a previously captured registry snapshot.
snapshot() → ChartRegistrySnapshot: Captures the current registry state for later restore.
suggestTypeStrings(String rawType, {int limit = 3}) → List<String>: Suggest registered type strings for a mistyped or unregistered rawType.
unregister(ChartType type) → void: Remove a chart type from the registry (e.g. for testing).
withRegistrations<T>(Iterable<ChartRegistration> registrations, T body(), {bool clearBefore = false}) → T: Temporarily registers registrations while synchronous body runs, then restores the previous registry state even when body throws.
withRegistrationsAsync<T>(Iterable<ChartRegistration> registrations, Future<T> body(), {bool clearBefore = false}) → Future<T>: Async variant of withRegistrations.
withTag(String tag) → List<ChartRegistration>: All registrations with a given tag.
