Laravel image uploaded successfully test failed

This is my store method

  DB::transaction(function () use ($request) {
      $imageName = LocalHubHelper::renameImageFileUpload($request->file('image'));
      $request->file('image')->move(public_path('storage/uploads/flyers'), $imageName);
      Flyer::create([
          'title'              => $request->input('title'),
          'description'        => $request->input('description'),
          'image'              => $imageName,
          'order'              => $request->input('order'),
          'button_text'        => $request->input('button_text'),
          'button_link'        => $request->input('button_link'),
          'post_id'            => $request->input('post_id'),
      ]);
  });

and this is my factory

  public function definition()
  {
      return [
          'title'             => $this->faker->words(5,true),
          'description'       => $this->faker->realText(50),
          'order'             => 1,
          'post_id'           => Post::factory()->create()->id,
          'button_text'       => null,
          'button_link'       => '#',
          'image'             => UploadedFile::fake()->image('file.png', 250, 150),
          'created_at'        => now(),
          'updated_at'        => now(),
      ];
  }

and this is my test

    public function test_flyer_image_uploaded_successfully()
    {
        $this->signIn();
        $this->withoutExceptionHandling();
        Storage::fake('local');
        $file = UploadedFile::fake()->image('file.png', 250, 150);
        $attributes =  Flyer::factory()->raw(['image' => $file]);
        $response = $this->post($this->endPoint,$attributes)
            ->assertStatus(302);
        $imageName = Flyer::latest()->first()->image;
        Storage::disk('local')->assertExists("public/uploads/flyers/".$imageName);
    }

and this is the failed message

1) Tests\Feature\FlyerTest::test_flyer_image_uploaded_successfully
Unable to find a file at path [public/uploads/flyers/file_20210910.png].
Failed asserting that false is true.

but if I check storage/app/public/uploads/flyers then there is a file with this name. Am I asserting in different path?
