allowOverflow method Null safety

void allowOverflow(
  1. String name,
  2. bool allowed

Toggles whether the channel should show warning messages when discarding messages due to overflow.

This is expected to be called by platform-specific plugin code (indirectly via the control channel), not by code on the framework side. See handleMessage.

Calling this from framework code is redundant since by the time framework code can be running, it can just subscribe to the relevant channel and there is therefore no need for any messages to overflow.

This method has no effect in release builds.


void allowOverflow(String name, bool allowed) {
  assert(() {
    _Channel? channel = _channels[name];
    if (channel == null && allowed) {
      channel = _Channel();
      _channels[name] = channel;
    channel?.debugEnableDiscardWarnings = !allowed;
    return true;
