Deeplink metamask://wc?uri=wc:..... broken in versión 6.5.0

[jcorreapa]

Describe the bug
I am developing a native mobile application in Flutter, for this I use the library [https://pub.dev/packages/walletconnect_dart], at the moment of making the connection and generating the Uri, a uri of the type 'wc:... @1?bridge=https%3A%2F%2Fg.bridge.walletconnect.org&key=....'.

Before the current version 6.5.0, to open the metamask app, it worked perfectly for IOS and Android with the following structure: launchUrlString('metamask://wc?uri=$uri', mode: LaunchMode.externalApplication). But with the current version it stopped working, because although the app is opened, the connection modal is not shown.

It is not a problem of the library used, because when opening the application with the following structure: launchUrlString(uri, mode: LaunchMode.externalApplication), the modal is displayed. Which is not suitable for me, as this will open any wallet that supports the wc protocol, and my app only supports Metamask mobile.

You posted the same code for "incorrect" and "correct", which is the code that is working for you? I have similar problem too, but with a native Android app (Kotlin)

This code dost work correctly and don't show modal in my case only on some Android devices:
launchUrlString('metamask://wc?uri=$uri', mode: LaunchMode.externalApplication)

But this code works perfectly
launchUrlString('$uri', mode: LaunchMode.externalApplication)

To open Metamask, and not other crypto wallets, I like many developers, use the special prefix "metamask://wc?uri=$uri". But it seems that after a recent update, the Metamask team changed some data associated with deep links, and they stopped working correctly.

[idelburgo-iomob]

I have tried all these (Im in a native app in Kotlin):

• link as "metamask://wc?uri=$uri" -> opens metamask but no modal to connect
• link as "wc://wc?uri=$uri" -> let me select which wallet to use, selecting metamask but no modal to connect
• link as "$uri" -> let me select which wallet to use, selecting metamask returns to my app with instant "Session rejected"

This error broke my implementation that was working prior to this version.

Any suggestion to make it work again?

It's true, I just edited it. The one that really works is the: launchUrlString(uri, mode: LaunchMode.externalApplication)

    launchUrlString(
            _uri,.
            mode: LaunchMode.externalApplication,.
          ); 

I can connect on Android, but no connection modal on iOS. I've been having trouble for a month.
When will it be fixed?

any update on this?

@unicorndev99 are you sure about it? It does not work for me. 😢

If someone managed to connect to Metamask using the Flutter WalletConnect library, please write an example of how you implemented it! Or attach links to instructions for connecting WalletConnect with Metamask.

@unicorndev99 the issue I am seeing is universal links are working but deep links are not.
Is it working for you with a deep link on iOS?

Guys check this issue we discuss some points how to resolve problems with connections.

Closing this issue as it seems that the new MetaMask wallet solved it along side this.
