Displaying a flash message using Laravel - php

Question

I am trying to have some sort of a pop up screen or flash message using Laravel, currently I have set up a route and which is triggerd using Ajax call, which is submitting a field to a Controller method to verify if a certain user has any violations, when clicking the button "check for violation" nothing is happening and I am not getting any flash messages in my page.
here is my view:
#if(Session::has('success'))
<script type="text/javascript">
swal({
title:'Info!',
text:"{{Session::get('success')}}",
timer:5000,
type:'info'
}).then((value) => {
location.reload();
}).catch(swal.noop);
</script>
#endif
<form action="{{ route('assignees.store') }}" enctype="multipart/form-data" method="POST">
#csrf
<div class="row">
<div class="col-xs-4 col-sm-4 col-md-4">
<div class="form-group">
<strong>Customer ID:</strong>
<input class="form-control" type="text" name="custidno" id='cust' required autocomplete="off" onkeypress="myFunction()" placeholder="Customer ID" >
<button onclick="CheckViolation()"class="btn-info"type="button">Check for Violation</button>
</div>
</div>
JS Code
function CheckViolation()
{
var customerid= document.getElementById("cust").value;
var url = "{{ url('violationcheck') }}";
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
}
};
xhttp.open("GET", url + "?" +"custidno=" + customerid, true);
xhttp.send();
}
and that's my route:
Route::get('violationcheck', 'ViolationController#violationcheck')->name('violationcheck');
and that's my basic controller method
public function violationcheck(Request $request)
{
$custidno = customer::select("id")
->where('name',$request->custidno)
->first();
$checked = DB::table('violations')
->select('severity',DB::raw('count(*) as total'))
->where("customer_id",$custidno->id)
->where("status",1)
->groupBy('severity')
->first();
if(empty($checked))
{
$msg="No Violation found";
}else{
$msg="Violation found";
}
return redirect()->route('assignees.create')->with("success",$msg);
}
what am I doing wrong?

Try this one:
#if (session('info'))
<div class="alert alert-info">
{{ session('info') }}
</div>
#endif
