readLineSync method
Use this to read a whole line, whether in mock mode or with real stdin.
Implementation
String? readLineSync({encoding}) {
if (mock) {
var ret = _mockBuffer[0];
_mockBuffer.removeAt(0);
if (informStdout != null && (_isTest || _getEchomode())) {
informStdout!.write(ret);
}
return ret;
}
return stdin.readLineSync(encoding: encoding);
}
