dataId property
An identifier for the data on which a data breakpoint can be registered
with the setDataBreakpoints request or null if no data breakpoint is
available. If a variablesReference or frameId is passed, the dataId
is valid in the current suspended state, otherwise it's valid
indefinitely. See 'Lifetime of Object References' in the Overview section
for details. Breakpoints set using the dataId in the
setDataBreakpoints request may outlive the lifetime of the associated
dataId.
Implementation
final Either2<String, Null> dataId;
