Good catch, I've fixed this in 3adef15.

I am using the latest version but it still returns true! :(

web3dart 2.1.4

I've just published version 2.2.0 which contains the fix.

I can't reproduce this. We have this example:

web3dart/example/metamask/web/main.dart

Lines 9 to 13 in 4edbfd7

 final eth = window.ethereum; 
 if (eth == null) { 
   print('MetaMask is not available'); 
   return; 
 } 

When I run dart pub global webdev serve, it prints "MetaMask is not available" in a browser without metamask and opens the pop-up for browsers that have the plugin installed.

no no
I did not mean that!

if (eth != null)
eth!.isConnected();

isConnected()

What is the task of this?

because this function always return true with eth != null !!

In fact, I want to check to see do my dApp is connect to the metamask or not

for example if not connect, I call
eth!.requestAccount();
