Update examples (blurhash) about octo_image HOT 4 OPEN

For those interested, I fixed on my side by introducing this class :

class OctoBlurHashFix {
  static OctoPlaceholderBuilder placeHolder(String hash, {BoxFit? fit}) {
    return (context) => SizedBox.expand(
      child: Image(
        image: BlurHashImage(hash),
        fit: fit ?? BoxFit.cover,
      ),
    );
  }

  static OctoErrorBuilder error(
      String hash, {
        BoxFit? fit,
        Text? message,
        IconData? icon,
        Color? iconColor,
        double? iconSize,
      }) {
    return OctoError.placeholderWithErrorIcon(
      placeHolder(hash, fit: fit),
      message: message,
      icon: icon,
      iconColor: iconColor,
      iconSize: iconSize,
    );
  }
}

Then, replace your usages of OctoError.blurhash and OctoPlaceholder.blurhash :

OctoImage(
    colorBlendMode: BlendMode.modulate,
    fit: BoxFit.cover,
    image: CachedNetworkImageProvider(imageUrl),
    placeholderBuilder: OctoBlurHashFix.placeHolder(placeHolderBlurHashString),
    errorBuilder: OctoBlurHashFix.error(errorBlurHashString, iconColor: Colors.transparent),
 ),

You may also have to add the blurhash dependency
flutter_blurhash: ^0.8.2

from octo_image.

I'm also using OctoImage with blurHash and it works great for ^1.0.2. It'd be great if you could document how to migrate to ^2.0.0 and overcome this.

from octo_image.

same .blurHash is not defined

from octo_image.

/// Simple set to show [OctoPlaceholder.circularProgressIndicator] as
/// placeholder and [OctoError.icon] as error.
OctoSet blurHash(
String hash, {
BoxFit? fit,
Text? errorMessage,
}) {
return OctoSet(
placeholderBuilder: blurHashPlaceholderBuilder(hash, fit: fit),
errorBuilder: blurHashErrorBuilder(hash, fit: fit),
);
}

OctoPlaceholderBuilder blurHashPlaceholderBuilder(String hash, {BoxFit? fit}) {
return (context) => SizedBox.expand(
child: Image(
image: BlurHashImage(hash),
fit: fit ?? BoxFit.cover,
),
);
}

OctoErrorBuilder blurHashErrorBuilder(
String hash, {
BoxFit? fit,
Text? message,
IconData? icon,
Color? iconColor,
double? iconSize,
}) {
return OctoError.placeholderWithErrorIcon(
blurHashPlaceholderBuilder(hash, fit: fit),
message: message,
icon: icon,
iconColor: iconColor,
iconSize: iconSize,
);
}

is this the way?
