get user data on post request in laravel

i just starting to learn laravel and i don't know how to pass data on controller

this is my routes.php

Route::get('/', 'view@index');
Route::get('/create', 'view@create');
Route::get('/store', 'view@store');
Route::post('/destroy', 'view@destroy');

and this is my controller

<?php namespace App\Http\Controllers;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;

use App\Http\Request;

class view extends Controller {


public function index()
{
   echo $data = User::all();
}


public function create()
{



   $user =  User::create(['first_Name'=>'abc']);
     echo "id =".$user->id." is created";

}

public function store()
{
    echo "store";
}

/* here i want to get id using post request */

public function destroy(Request $request)
{
    $id = $request->input('id');
    echo $id;
  /
 }

}

now i want to pass 'id' using postman in post request. how can i perform this. my get request working perfectly
