addBreakpointAtEntry method Null safety
The addBreakpointAtEntry
RPC is used to add a breakpoint at the
entrypoint of some function.
If no breakpoint is possible at the function entry, the 102
(Cannot add
breakpoint) RPC error
code is returned.
If isolateId
refers to an isolate which has exited, then the Collected
Sentinel is returned.
See Breakpoint
.
Note that breakpoints are added and removed on a per-isolate basis.
This method will throw a SentinelException in the case a Sentinel is returned.
Implementation
Future<Breakpoint> addBreakpointAtEntry(String isolateId, String functionId);
