Redirect after download file laravel 5.7 - php

Question

Hello there
Hope you will be doing well.I want to redirect to a route after file download but as we know that return only works once in a controller method how i can achieve this with laravel 5.7.I have to set a session and display it when data exported in txt file.I want this with post method.
Every thing is fine but redirect is not working;
Controller Method
public function exportTxtProcess(Request $request)
{
$table = $request->tblExportSelect;
$destinationPath = public_path('/');
$result;
$outputs = DB::select("SELECT * FROM $table");
$today = date("Y-m-d");
$fileName = $table . "-" . $today;
$fp = fopen($destinationPath . "$fileName.txt", "wb");
foreach ($outputs as $output) {
$output = (array)$output;
#array_shift($output);
$removeUserId = #$output['user_id'];
$created_at = #$output['created_at'];
$updated_at = #$output['updated_at'];
if (($key = array_search($removeUserId, $output)) !== false) {
unset($output[$key]);
}
if (($key1 = array_search($created_at, $output))) {
unset($output[$key1]);
}
if (($key2 = array_search($updated_at, $output))) {
unset($output[$key2]);
}
if (is_null($created_at) OR $created_at == '') {
unset($output['created_at']);
}
if (is_null($updated_at) OR $updated_at == '') {
unset($output['updated_at']);
}
$netResult = $this->getTableFields($table, $output);
fwrite($fp, $netResult);
}
$result = fclose($fp);
if ($result) {
$pathToFile = $destinationPath . "$fileName.txt";
$redirect = redirect()->back();
$sess = Session::flash('success', 'Table exported successfully');
return response()->download($pathToFile)->deleteFileAfterSend(true);
}
}
Thank in advance

You can only have 1 response, so it's impossible to instruct a double
return. What you could do, is set the filename you wish to have
downloaded in a session variable, then redirect back to whatever page.
Within the redirected page, you could flash your message, along with
having an automatic download of the file.
