  • flutterda unique ekranlar oluşturma

İyi günler arkadaşlar. Bir tane ödevim var flutterla ilgili uygulama yapıyorum o yüzden sorunumu hızlı çözebilirseniz beni çok mutlu edersiniz. Flutterda bir anasayfa üzerinde scroll üzerinde kayan resimler koydum ve bunlar tıklanabilir halde. hero widgeti kullandım. Bu resimlerden birine tıkladığımızda örneğin o resimle ilgili sayfa açılıyor genel olarak hep aynı tarz sayfa olacak fakat bazı özellikleri değiştirilmesi lazım bu resimlerin sayfalarının her biri için. Ama bu daha sonra açılan sayfaları çoğalttığımda sadece sayfada açılan resim ikonu değişiyor, diğer bilgileri değiştirmeye çalıştığımda aynı hero widgetini bu şekilde kullanamazsın gibi bir hata veriyor. Yani aslında bu çoğalttığım ekrnların her birini unique hale getirmem gerekiyor fakat bunu kod üzerinde nasıl yapacağımı bilmiyorum.

    Ivan ======== Exception caught by scheduler library =====================================================
    The following assertion was thrown during a scheduler callback:
    There are multiple heroes that share the same tag within a subtree.

    Within each subtree for which heroes are to be animated (i.e. a PageRoute subtree), each Hero must have a unique non-null tag.
    In this case, multiple heroes had the following tag: assets/images/5.png
    Here is the subtree for one of the offending heroes: Hero
    tag: assets/images/5.png
    state: HeroState#d68d9
    When the exception was thrown, this was the stack:

                  Bu şekilde anlaması güç oluyor hocam.
                  Asıl hata aldığınız yeri bir görselle eklerseniz, yanına da github link koyarsanız daha iyi olur. Bu şekilde biraz zor olacaktır.

                    hocam birden fazla Hero özelliği bulunan yapıların her birine farklı farklı isimler ver. Buna benzer hataları ben FloatinnActionButton larda almıştım. onlarda da herotag özelliği vardır. her birine Stringolarak farklı bir isim verdim ve hatalarım gitmişti. Sende bir Hero yapısı var ve hepsinde tagözelliği aynı. hepsi image. bunları tekil hale getirmeyi bir dene.
