How to Fix unable to load asset Flutter

How to Fix unable to load asset Flutter – Assets are static files included in the compiled Flutter app and available at runtime. Images, fonts, movies, sounds, and other media are just few examples of the many file kinds that can make up these assets.

To update a Flutter project with new assets, the “pubspec.yaml” file must be edited. This file is a configuration file that details the project’s resources and requirements.

How to Fix unable to load asset Flutter

If you are unable to load assets Flutter, there are several possible reasons and solutions:

  • Verify the “pubspec.yaml” file contains accurate asset declarations. Make sure the paths to the assets are relative to the “assets” directory and that the indentation is right.

  • Check your project’s “assets” directory. If they’re in a subdirectory, include the path in the asset declaration.

  • Check file names and extensions. If you’re loading an image, make sure it’s “.png” or “.jpg.”
  • If you are using hot reload, try performing a full restart of the application. Hot reload sometimes does not work correctly with assets.
  • To clear the build cache and recompile the project if the asset is not loading properly, type “flutter clean” into the terminal.

  • If none of those work, you can always try loading the asset explicitly using the “rootBundle” object. This object, of type “AssetBundle,” has access to methods for loading assets in various formats, including bytes, strings, and data streams.

Example of how to load an image asset using the rootBundle object in Flutter:

import 'package:flutter/services.dart';
import 'package:flutter/material.dart';

class MyImageWidget extends StatelessWidget {
  Widget build(BuildContext context) {
    return FutureBuilder(
      future: loadImageAsset(context, 'assets/images/my_image.png'),
      builder: (BuildContext context, AsyncSnapshot snapshot) {
        if (snapshot.connectionState == ConnectionState.done) {
          return Image(image: snapshot.data);
        } else {
          return CircularProgressIndicator();

  Future loadImageAsset(BuildContext context, String assetPath) async {
    final ByteData data = await rootBundle.load(assetPath);
    final Uint8List bytes = data.buffer.asUint8List();
    final ImageProvider imageProvider = MemoryImage(bytes);
    return imageProvider;

The app’s assets/images directory has the my image.png image asset, which is loaded by a widget called MyImageWidget. An Image widget can show a picture by calling the rootBundle object’s loadImageAsset() method, which retrieves the image data and converts it into a MemoryImage object.


Loading indicators are displayed when images are being loaded while using the FutureBuilder widget. In order to display the image, the Image widget uses the ImageProvider that was returned by the loadImageAsset() method after the image has been loaded. It’s important to remember that setting the Image widget’s width and height or enclosing it in a widget that gives constraints, like a Container or AspectRatio, can help ensure that the ImageProvider is displayed correctly in the Image widget.

Specifically noteworthy is the Flutter asset system, which facilitates the simple addition of media files, typefaces, and other resources to a project’s app. The caching, preloading, and on-demand loading capabilities of this technology significantly improve app speed and decrease wait times.

The assets that Flutter provides are essential to its goal of expediting, simplifying, and optimizing the app development process. Its asset structure makes it simple for programmers to add necessary components to their apps, guaranteeing that they will provide customers with a functional, up-to-date mobile app.
