Update (Using laravel 8): Now that I've re-checked the typo errors. I'm getting the error below (upon articles/create):

BadMethodCallException Method Illuminate\Validation\Validator::validateRequried does not exist.

http://127.0.0.1:8000/articles

Controller code:

namespace App\Http\Controllers; use App\Models\Article; use Illuminate\Http\Request;

class ArticlesController extends Controller {

public function index(){
    //renders a list of resource
    //$articles = Article::paginate(2)->firstorfail();
    $articles = Article::latest()->get();
    
    return view('articles.index', [
        'articles' => $articles
    ]);

}
public function show(Article $article){
    
    //show a single resource

    //$article = Article::find($id);

    return view('articles.show', ['article' => $article]);
}

public function create(){
    //shows a view to create a new resource
     return view('articles.create');
}

public function store(){
    //persist the new resource
    //dump(request()->all());

    request()->validate([
        'title' => 'requried',
        'excerpt' => 'required',
        'body' => 'required'
    ]);

    $article = new Article();
    $article->title = request('title');
    $article->excerpt = request('excerpt');
    $article->body = request('body');
    $article->save();

    // the code above can be replace with Article::create() method below
    // Article::create([
    //     'title' => request('title'),
    //     'excerpt' => request('excerpt'),
    //     'body' => request('body')
    // ]);

    return redirect('/articles');
}

public function edit($id){
    //show a view to edit existing resource
    $article = Article::find($id);
    //return view('articles.edit', ['article' => $article]);
    return view('articles.edit', compact('article'));
}

public function update($id){
    //persist an edited resource
    request()->validate([
        $title = 'requried',
        $excerpt = 'required',
        $body = 'required'
    ]);

    $article = Article::find($id);

    $article->title = request('title');
    $article->excerpt = request('excerpt');
    $article->body = request('body');

    $article->save();

    return redirect('/articles/'. $article->id);
}

public function destroy(){
    //delete the resource
}
