install static method
Installs a TracingDelegate for the current isolate.
Only one TracingDelegate can be installed for a single isolate at any given moment.
Whether a TracingDelegate has been installed for this isolate can be checked with hasBeenInstalled.
Implementation
static Future<void> install(TracingDelegate delegate) async {
if (_hasBeenInstalled) {
throw StateError('A TracingDelegate has already been installed.');
}
_hasBeenInstalled = true;
currentTracingDelegate = delegate;
await addPostIsolateInitTask(delegate.initialize);
}
