TelemetryContext class
Additional information to be attached to telemetry items produced by a TelemetryClient.
A TelemetryContext is mutable wrapper around a Map<String, dynamic>. Every TelemetryClient has an instance of TelemetryContext that will be attached to each telemetry item produced by it.
Most of the properties on this type, such as device and user, are provided for convenience. They allow you to easily get or set contextual information for commonly-known Application Insights properties without needing to know the property keys. All properties, regardless of whether they're well-known or custom ones, can also be accessed via properties.
