較新的extended_image（自0.5.3起）包含了一些非向前兼容的改動白对，使得該依賴無法在Flutter SDK版本低于1.7.8（穩(wěn)定版）的環(huán)境下使用颓遏。
若您需要在低于SDK版本低于1.7.8（比如1.5.4）的環(huán)境下使用該依賴虚茶，必須在pubspec.yaml內(nèi)同時指定extended_image和extended_image_library為指定或更低的版本，如代碼所示狂票。
我們?nèi)匀粡娏医ㄗh您使用最新的穩(wěn)定渠道的Flutter SDK龟再。
extended_image for v1.7.8
extended_image: 0.5.5
extended_image_library: 0.1.4
