info: ‘typed’ is deprecated and shouldn’t be used. Use stream.cast instead.

// だめ
final stream = http.ByteStream(DelegatingStream.typed(image.openRead()))

// ok
final stream = http.ByteStream(image.openRead())..cast<dynamic>();

// だめ

final stream = http.ByteStream(DelegatingStream.typed(image.openRead()))

// ok

final stream = http.ByteStream(image.openRead())..cast<dynamic>();

これでいけました
