Route [inventory.orderShirt] not defined.

I am making a page where there are 3 tables. Inventory, Rate, and Order. Inventory and Rate alone is working. but adding the order gives me that error.

shows.blade

//rating
 {!! Form::open(array('route' => array('inventory.showRate', $inventories->id), 'method'=>'POST')) !!}
                        

                            {{Form::label('rating','Rating')}}

                            {{Form::select('rating', ['1' => '1', '2' => '2', '3' => '3', '4' => '4', '5' => '5'], '3', ['placeholder' => 'Select rating'])}}  
                        
     
                        

{{Form::submit('Submit', ['class'=>'btn btn-primary'])}} 
//inventory
ID
{$inventories->id}}
Name
{{$inventories->name}}
//order
{!! Form::open(array('route' => array('inventory.orderShirt', $inventories->id), 'method'=>'POST')) !!}


{{Form::submit('Submit', ['class'=>'btn btn-primary'])}}



{!! Form::close()!!}

controller.php

    public function shows($id)
    {
        $inventories =  Inventory::find($id);                
        return view('inventory.show')->with('inventories', $inventories);

        
    }
    public function showRate(Request $request, $id)
    {   
        $inventories =  Inventory::find($id); 
        //create rating
        $ratings = new Rating;
        $ratings->rating = $request->input('rating');
        $ratings->inv_id = $inventories->id;
        $ratings->user_id = auth()->user()->id;
        $ratings->save();

        return redirect('/store')->with('success','Rating updated');
    }
    public function orderShirt(Request $request, $id)
    {
        $inventories =  Inventory::find($id);  
        //create order
        $orders = new Order;
        $orders->order_id = Str::random(20);
        $orders->inv_order_id = $inventories->id;
        $orders->user_order_id = auth()->user()->id;
        $orders->save();

        return redirect('/store')->with('success','Order complete!');

        // ->with('success','order added');

    }

web.php

Route::post('/store/{id}','InventoryController@orderShirt')->name('inventory.orderShirt'); 
Route::post('/store/{id}','InventoryController@showRate')->name('inventory.showRate'); 
Route::get('store/{id}', 'InventoryController@shows')->name('inventory.shows');

I hope you could help me! Thank you in advance :) P.S. I am using laravel collective
