launchdarkly_common_client library

Classes

ApplicationInfo
Application metadata may be used by LaunchDarkly analytics or other product features.
AttributeReference
An attribute name or path expression identifying a value within an LDContext.
CommonPlatform
CredentialSource
Allows loading a credential, either a client-side ID or mobile key, from environment variables.
DataSourceConfig
DataSourceStatus
DataSourceStatusErrorInfo
A description of an error condition that the data source encountered.
DiagnosticSdkData
EventsConfig
Configuration for event processing and sending.
FlagsChangedEvent
This event indicates that the details associated with one or more flags have changed.
HttpProperties
IdentifyComplete
The identify has been completed. Either the identify completed with cached data, or new data was fetched from LaunchDarkly.
IdentifyError
The identify operation encountered an error and will not complete.
IdentifyResult
Base class used for all identify results. Using a sealed class allows for exhaustive matching the the return from identify operations.
IdentifySuperseded
The identify has been superseded. Multiple identify calls were outstanding and this one has been cancelled.
LDBasicLogPrinter
Basic log printer which will output all messages using print.
LDCommonClient
LDCommonConfig
Configuration common to dart based SDKs.
LDContext
A collection of attributes that can be referenced in flag evaluations and analytics events. A LDContext may contain information about a single context or multiple contexts differentiated by the "kind" attribute.
LDContextBuilder
A builder to facilitate the creation of LDContexts. Note that the return type of kind is a LDAttributesBuilder that is used to define attributes for the specific kind of context you are creating.
LDEvaluationDetail<T>
Class returned by the "variation detail" methods such as LDClient.boolVariationDetail, combining the result of the evaluation with an explanation of how it was calculated.
LDEvaluationReason
Describes the reason that a flag evaluation produced a particular value.
LDLogAdapter
Interface used by log printers for use with the SDK. A custom implementation can be used to adapt the SDK log output to a logging framework of your choice.
LDLogger
Logging implementation used by the SDK. A default constructed logger will enable the LDLogLevel.info level and will output messages using the LDBasicLogPrinter.
LDLogRecord
Represents a log entry from LDLogger. It can be used with an LDLogAdapter to control logging output from the SDK.
LDValue
An immutable instance of any data type that is allowed in JSON.
LDValueArrayBuilder
Builder for constructing an LDValueType.array typed LDValue.
LDValueObjectBuilder
Builder for constructing an LDValueType.object typed LDValue.
Persistence
Interface for a data store that holds feature flag data and other SDK properties in a serialized form. Implementations should maintain an in-memory cache of previously read or written values for performance.
PersistenceConfig
Configuration which affects how the SDK uses persistence.
ServiceEndpoints
Specifies the base service URLs used by SDK components.

Enums

AutoEnvAttributes
Enable / disable options for Auto Environment Attributes functionality. When enabled, the SDK will automatically provide data about the mobile environment where the application is running. This data makes it simpler to target your mobile customers based on application name or version, or on device characteristics including manufacturer, model, operating system, locale, and so on. We recommend enabling this when you configure the SDK. See https://docs.launchdarkly.com/sdk/features/environment-attributes for more documentation.
ConnectionMode
The connection mode for the SDK to use.
DataSourceState
LDErrorKind
Enumerated type defining the defined error cases for an LDEvaluationReason with the kind LDKind.error.
LDKind
Enumerated type defining the possible reasons for a flag evaluation result, used in LDEvaluationReason.
LDLogLevel
Logging levels that can be used with LDLogger. Set the log level to one of these values when constructing a LDLogger to control level of log messages are enabled. Going from lowest importance (and most verbose) to most importance, the levels are: LDLogLevel.debug, LDLogLevel.info, LDLogLevel.warn, and LDLogLevel.error. You can also specify 'none' instead to disable all logging.
LDValueType
Describes the type of an LDValue. These correspond to the standard types in JSON.
