Support mdns when attaching to proxied devices. by chingjun · Pull Request #146021 · flutter/flutter

Also move the vm service discovery logic into platform-specific implementation of Devices. This is to avoid having platform-specific code in attach.dart.

+ },
+ onError: (Object e) {

Is it safe to ignore other errors here?

Good point. Forwarded the error to the stream instead.

+ timeout: const Duration(seconds: 30),
+ slowWarningCallback: () {
+ // If relying on mDNS to find Dart VM Service, remind the user to allow local network permissions.
+ if (vmServiceDiscovery.usesMdns) {


This status message is only relevant to iOS devices.
Suggested change
if (vmServiceDiscovery.usesMdns) {
if (vmServiceDiscovery.usesMdns&&_isIOSDevice(device)) {

You made me realize that I misunderstood the comment and the message. I thought it was asking me to click "Allow" on the mac, when the dart binary wants to access network. It makes a lot more sense now.
In that case, usesMdns is not actually needed, I've removed that field. I also updated the comment and the message slightly to be clear that the permission.
Also updated _isIOSDevice below to check for device.platformType == PlatformType.ios instead of checking the type, to better support proxied devices.
PTAL, thanks!

+ } on Exception {
+ isolateDiscoveryProtocol?.dispose();
+ final List<ForwardedPort> ports = portForwarder.forwardedPorts.toList();
+ ports.forEach(portForwarder.unforward);


So previously, it was
flutter/packages/flutter_tools/lib/src/commands/attach.dart
Lines 309 to 311 in 137cb4b
for (finalForwardedPort port in ports) {
await device.portForwarder.unforward(port);
}
Does putting it in a forEach wait for each?

On re-reading the code, the try-catch was not added in the right place. I have moved it to the Stream<Uri> get uris getter below, and added the await back.
Thanks.

This LGTM but I'll defer to Victoria for final approval (she knows this code the best)

Removed `usesMdns`, and restore platform checking in attach.dart when showing the message asking user to allow network access on device. Fix error handling in FuchsiaDevice.

LGTM!
