Decoded image has been disposed

🐛 Bug Report

Expected behavior

Should load the image correctly.

Reproduction steps

I'm checking how much memory is currently in the cache and then cleaning the cache when full.

I'm receiving the following logs on Crashlytics:

Non-fatal Exception: io.flutter.plugins.firebase.crashlytics.FlutterError: Exception: Decoded image has been disposed. Error thrown null.
       at FirebaseCrashlytics.recordError(firebase_crashlytics.dart:119)
       at CustomExtendedImage.build.<fn>(custom_extended_image.dart:72)
       at CachedNetworkImage._octoErrorBuilder(cached_image_widget.dart:318)

Check the code:

void _checkMemory() {
    late int maxBytes;
    final ConfigProvider configProvider = locator<ConfigProvider>();
    if (Platform.isAndroid) {
      maxBytes = 1024 * 1024 * 100 * configProvider.androidMaxCache; // 500 MB
    } else {
      maxBytes = 1024 * 1024 * 100 * configProvider.iOSMaxCache; // 400 MB
    }
    FirebaseCrashlytics.instance
        .log('Max bytes in cache for images: ${maxBytes.toString()}');

    ImageCache _imageCache = PaintingBinding.instance.imageCache;
    if (_imageCache.currentSize >= 400 ||
        _imageCache.currentSizeBytes >= maxBytes) {
      FirebaseCrashlytics.instance.log(
          'Current image cache size: ${_imageCache.currentSizeBytes}. Its greater than the max: ${maxBytes.toString()} or greater than 400mb.\nCleaning images from cache.');

      _imageCache.clearLiveImages();
      _imageCache.clear();

      FirebaseCrashlytics.instance.log('Images removed from cache.');
      return;
    }
  }

  @override
  Widget build(BuildContext context) {
    final int? cacheWidthInt =
        cacheWidth ? MediaQuery.of(context).size.width.toInt() : null;
    final int? cacheHeightInt =
        cacheHeight ? MediaQuery.of(context).size.height.toInt() : null;
    _checkMemory();
    return CachedNetworkImage(
      imageUrl: url,
      fit: BoxFit.cover,
      height: height ?? MediaQuery.of(context).size.height,
      width: width ?? MediaQuery.of(context).size.width,
      placeholderFadeInDuration: Duration.zero,
      fadeInDuration: Duration.zero,
      fadeOutDuration: Duration.zero,
      errorWidget: (context, url, error) {
        FirebaseCrashlytics.instance.log(
          'An error occur loading image: $url\nShowing error placeholder.',
        );

        FirebaseCrashlytics.instance.recordError(error, null);

        return const Icon(Icons.error);
      },
      memCacheWidth: cacheWidth ? (cacheWidthInt! * 1.5).toInt() : null,
      color: color,
      filterQuality: FilterQuality.medium,
      memCacheHeight: cacheHeight ? (cacheHeightInt! * 1.4).toInt() : null,
    );
}

I'm facing the same issue. Not sure how to reproduce but I'm seeing some reports on the crashlytics tool we use
