Describe the problem

Connection errors while establishing a connection with WebSocketChannel.connect() can't be handeled with try/catch blocks.

Expected fix

No response

Additional context

Establishing connections to a none available server causes my app to crash even though I am trying to catch the error in a try/catch block

WebSocketChannel channel = WebSocketChannel.connect(
    Uri.parse('ws://localhost:8000/ws'),
);

try {
    await channel.ready;
} catch (e) {
    print("Exception: $e");
}
