var attempts = 0;

while (isLoopContinue == true) {
stdout.writeln("Enter email:");
var email = stdin.readLineSync();
stdout.writeln("Enter password:");
var password = stdin.readLineSync();
if (email == 'admin-gmail.com' && password == "123456") {
print("Login successfully");
isLoopContinue = false;
} else {
attempts++;

isLoopContinue = false;
print('Your account has been blocked!');

Code RUNS OK when we run this code via CMD by running this command "dart run filename.dart"

The vscode default debug console does not accept user input. To debug a program requiring user input you will have to set: Preferences > Dart > Run and Debug > Dart: Cli Console to Terminal (or alternatively External Terminal).

[sarvesh2847]

By default, the application runs without a terminal. The "Debug Console" you are using is a REPL (Read-Eval-Print Loop) that processes expressions and displays the results.

If you need to read input from stdin, you'll have to configure the extension to run inside a terminal instead. However, this mode may have limited functionality since the debugger will have less access to the process output.

There are two ways to run the application in the terminal: one is by setting the console field in a launch.json file, and the other is by configuring the dart.cliConsole setting in your VS Code User or Workspace Settings, depending on whether you want the change to apply to all projects or just this one.
