How to show snackBar without Scaffold

Question

I am trying to show snackbar in my app to notify User but without scaffold it shows me error. My current code is:

scaffoldKey.currentState?.showSnackBar(
    new SnackBar(
      backgroundColor: color ?? Colors.red,
      duration: Duration(milliseconds: milliseconds),
      content: Container(
        height: 50.0,
        child: Center(
          child: new Text(
            title,
            style: AppTheme.textStyle.lightText.copyWith(color: Colors.white),
            overflow: TextOverflow.ellipsis,
          ),
        ),
      ),
    ),
  )

Answer 1

It can get the current context and show snackbar like this:

void _showToast(BuildContext context) {
  final scaffold = Scaffold.of(context);
  scaffold.showSnackBar(
    SnackBar(
      content: const Text('Updating..'),
    ),
  );
}

this._showToast(context);
