Methods

getAvailableCachedCpuSamples() → Future<AvailableCachedCpuSamples>

Available on VmService, provided by the DdsExtension extension

The getAvailableCachedCpuSamples RPC is used to determine which caches of CPU samples are available. Caches are associated with individual UserTag names and are specified when DDS is started via the cachedUserTags parameter.

getCachedCpuSamples(String isolateId, String userTag) → Future<CachedCpuSamples>

Available on VmService, provided by the DdsExtension extension

The getCachedCpuSamples RPC is used to retrieve a cache of CPU samples collected under a UserTag with name userTag.

getClientName() → Future<ClientName>

Available on VmService, provided by the DdsExtension extension

The getClientName RPC is used to retrieve the name associated with the currently connected VM service client.

getDartDevelopmentServiceVersion() → Future<Version>

Available on VmService, provided by the DdsExtension extension

The getDartDevelopmentServiceVersion RPC is used to determine what version of the Dart Development Service Protocol is served by a DDS instance.

getLogHistorySize(String isolateId) → Future<Size>

Available on VmService, provided by the DdsExtension extension

The getLogHistorySize RPC is used to retrieve the current size of the log history buffer.

getPerfettoVMTimelineWithCpuSamples({int? timeOriginMicros, int? timeExtentMicros}) → Future<PerfettoTimeline>

Available on VmService, provided by the DdsExtension extension

The getPerfettoVMTimelineWithCpuSamples RPC functions nearly identically to VmService.getPerfettoVMTimeline, except the trace field of the PerfettoTimeline response returned by this RPC will be a Base64 string encoding a Perfetto-format trace that includes not only all timeline events in the specified time range, but also all CPU samples from all isolates in the specified time range.

getStreamHistory(String stream) → Future<StreamHistory>

Available on VmService, provided by the DdsExtension extension

Retrieve the event history for stream.

onEventWithHistory(String stream) → Stream<Event>

Available on VmService, provided by the DdsExtension extension

Returns the stream for a given stream id which includes historical events.

postEvent(String stream, String eventKind, Map<String, Object?> eventData) → Future<void>

Available on VmService, provided by the DdsExtension extension

Send an event to the stream.

readyToResume(String isolateId) → Future<Success>

Available on VmService, provided by the DdsExtension extension

The readyToResume RPC indicates to DDS that the current client is ready to resume the isolate.

requirePermissionToResume({bool onPauseStart = false, bool onPauseReload = false, bool onPauseExit = false}) → Future<Success>

Available on VmService, provided by the DdsExtension extension

The requirePermissionToResume RPC is used to change the pause/resume behavior of isolates.

requireUserPermissionToResume({bool onPauseStart = false, bool onPauseExit = false}) → Future<Success>

Available on VmService, provided by the DdsExtension extension

The requireUserPermissionToResume RPC notifies DDS if it should wait for a VmService.resume request to resume isolates paused on start or exit.

setClientName([String name = '']) → Future<Success>

Available on VmService, provided by the DdsExtension extension

The setClientName RPC is used to set a name to be associated with the currently connected VM service client.

setLogHistorySize(String isolateId, int size) → Future<Success>

Available on VmService, provided by the DdsExtension extension

The setLogHistorySize RPC is used to set the size of the ring buffer used for caching a limited set of historical log messages.
