flutter doesn't see images from assets/images-CodePudding

I'm using spider to implement a dynamic photo upload builder, but for some reason Dart doesn't see photos from the assets/images folder

below are all the working files of the project that are involved

images.dart:

part of 'resources.dart';

class AppImages {
  AppImages._();

  static const String moviePlacholder = 'assets/images/movie_placholder.jpg';
}

  # To add assets to your application, add an assets section, like this:
assets:
    - assets/images/
  #   - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.dev/assets-and-images/#resolution-aware

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
fonts:
    - family: GrapeNuts
      fonts:
        - asset: assets/fonts/GrapeNuts-Regular.ttf
          weight: 400
  # fonts:
  #   - family: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700
  #
  # For details regarding fonts from package dependencies,
  # see https://flutter.dev/custom-fonts/#from-packages

}

class _MovieListWidgetState extends State<MovieListWidget> {
  @override
  Widget build(BuildContext context) {
    return ListView.builder(
        itemCount: 10,
        itemExtent: 163,
        itemBuilder: (BuildContext context, int index) {
          return SafeArea(
            child: Row(
              children: const [
                Image(image: AssetImage(AppImages.moviePlacholder))
              ],
            ),
          );
        });
  }
}

there are no errors in the code, but the crane does not display the image from the assets/mages folder

CodePudding user response：

Maybe simple solution but - did You stop and restart the app after adding assets?

I had the same problem, and it was happening because of hot restart/reload.

CodePudding user response：

Your asset path in your pubspec.yaml is wrong

Change

- images/

- assets/images/
