Call to a member function store() on null - laravel

Question

I'm just wondering why this doesn't work for my Item Controller however on other controller it worked.
Controller for Item
public function store(Request $request, $id)
{
$categories = Category::all();
$userId = Auth::user()->id;
$item = new Item;
$item->store_id = $userId;
$item->name = $request->name;
$item->description = $request->description;
$item->unit_price = $request->unit_price;
$path = $request->image->store('images', 'public');
$item->picture = $path;
$item->category_id = $request->category_id;
$item->is_available = 1;
$item->is_archived = 0;
$item->save();
return redirect('/store/index')->with('status', 'Item successfully added!');
}
HTML form for creating item data
<form method="post" action='{{ url("item/store/$stores->id") }}' enctype="mutlipart/form-data">
#csrf
<input placeholder="Item Name" type="text" name="name" value="{{ old('name') }}" required autocomplete="off">
<input placeholder="Item Description" type="text" name="description" value="{{ old('description') }}" required autocomplete="off">
<input placeholder="000.00" type="decimal" name="unit_price" value="{{ old('unit_price') }}" required autocomplete="off">
<input type="file" name="picture" required>
<label>Category</label>
<select class="form-control" name="category_id">
<option value selected disabled>Select Category</option>
#foreach ($categories as $category)
<option value="{{ $category->id }}">{{ $category->name }}</option>
#endforeach
</select>
<button type="submit" class="btn btn-warning">Add</button>
</form>
Thank you for answering

There are no any input file named image your input file name is picture.
if you have a file field, and you try to check it with $request->has(‘file’), it will always return FALSE. For files there is a specific method :
$path = $request->image->store('images', 'public');
$item->picture = $path;
Change to
$path = "no_image.png";
if ($request->hasFile('picture')) {
// $path = $request->picture->store('images', 'public');
$file = $request->picture;
$fName = time() . $file->getClientOriginalName();
$file->move('images', $fName );
$path = 'images/'.$fName;
}
$item->picture = $path;
