Methods

copyWith<T>(ContextKey<T> key, T value) → Context: Creates a new Context with the specified value for the given key
copyWithBaggage(Baggage moreBaggage) → Context: Creates a new Context adding in moreBaggage, replacing any existing keys that are the same as the keys in moreBaggage Creates a new Context with additional Baggage entries.
copyWithoutSpan() → Context: Creates a new Context without a span or span context
copyWithSpanContext(SpanContext spanContext) → Context: Creates a new Context with the given SpanContext.
copyWithValue<T>(String name, T contextValue) → Context: Creates a new Context with the specified value for the given key Creates a new Context with a new key-value pair added.
get<T>(ContextKey<T> key) → T?: Gets the value added for the ContextKey Returns null if no value is set for this key or if the value's type doesn't match T Gets a value from the context for the specified key.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
run<T>(Future<T> operation()) → Future<T>: Run an operation in a zone with this context
runIsolate<T>(Future<T> computation()) → Future<T>: Runs a computation in a new isolate with this context.
serialize() → Map<String, dynamic>: Serializes the context into a JSON-compatible map.
setCurrentSpan(APISpan? span) → Context: Sets this context as the current context with the given span active. This is separate from span creation as per the specification.
toString() → String: A string representation of this object.
inherited
withBaggage(Baggage baggage) → Context: Creates a new context with the given baggage Send an empty baggage to avoid sending any name/value pairs to an untrusted process.
withSpan(APISpan span) → Context: Creates a new Context with the given span set as active
withSpanContext(SpanContext spanContext) → Context: Creates a new context with the given span context

Operators

operator ==(Object other) → bool: The equality operator.
override

Static Properties

current ↔ Context: Gets the current Context from the current Zone, or the global Context if none exists.
getter/setter pair
root → Context: The root context with no values
no setter

Static Methods

clearCurrentSpan() → Context: Clears the current span from the context. Returns a new context without the span and span context.
currentWithBaggage() → Context: Returns the current context with Baggage, creating empty Baggage if needed.
deserialize(Map<String, dynamic> values) → Context: Deserializes a previously serialized context map back into a Context object.
resetCurrent() → void: Resets the current context to a new empty context.
resetRoot() → void: Resets the root context to a new empty context.
