Methods

The addBreakpoint RPC is used to add a breakpoint at a specific line of some script.
addBreakpointAtEntry(String isolateId, String functionId) → Future<Breakpoint>
The addBreakpointAtEntry RPC is used to add a breakpoint at the entrypoint of some function.
addBreakpointWithScriptUri(String isolateId, String scriptUri, int line, {int? column}) → Future<Breakpoint>
The addBreakpoint RPC is used to add a breakpoint at a specific line of some script. This RPC is useful when a script has not yet been assigned an id, for example, if a script is in a deferred library which has not yet been loaded.
callMethod(String method, {String? isolateId, Map<String, dynamic>? args}) → Future<Response>
Call an arbitrary service protocol method. This allows clients to call methods not explicitly exposed by this library.
callServiceExtension(String method, {String? isolateId, Map<String, dynamic>? args}) → Future<Response>
Invoke a specific service protocol extension method.
clearCpuSamples(String isolateId) → Future<Success>
Clears all CPU profiling samples.
clearHttpProfile(String isolateId) → Future<Success>

Available on VmService, provided by the DartIOExtension extension

The clearHttpProfile RPC is used to clear previously recorded HTTP requests from the HTTP profiler state. Requests still in-flight after clearing the profiler state will be ignored by the profiler.

Available on VmService, provided by the DartIOExtension extension

Removes all statistics associated with prior and current sockets.
clearVMTimeline() → Future<Success>
Clears all VM timeline events.
createIdZone(String isolateId, String backingBufferKind, String idAssignmentPolicy, {int? capacity}) → Future<IdZone>
The createIdZone RPC is used to create a new ID zone where temporary IDs for instances in the specified isolate may be allocated. See IDs and Names for more information about ID zones.
deleteIdZone(String isolateId, String idZoneId) → Future<Success>
The deleteIdZone RPC frees the buffer that backs the specified ID zone, and makes that zone unusable for the remainder of the program's execution. For performance reasons, clients should aim to call invalidateIdZone and reuse existing zones as much as possible instead of deleting zones and then creating new ones.
