Lobo ubuhle nekhono leFlutter. Manje, ake sixoxe ngezibuyekezo eziphezulu ezi-5 ku-Flutter 2.2.
Null Safety
Ngokukhishwa kwe-2.0, i-Flutter yethule isici se-Null Safety, manje esesiphenduke okuzenzakalelayo kumaphrojekthi amasha. Ngesici se-Null Safety, onjiniyela bangakhombisa kalula ukuthi ukuguquguquka noma inani lingaba ize noma cha, ngokuqondile kusuka kukhodi. Inikeza ukuvikeleka kokuhlukile kwesithenjwa esingenalutho.
Ngale ndlela, amaphutha ahlobene ne-null-pointer angancishiswa futhi alawulwe.
Eqinisweni, ngolimi lwe-Dart olusetshenziswa ku-Flutter, umhlanganisi uhlakaniphe ngokwanele ukuze asuse konke ukuhlola okungenalutho ngesikhathi sokusebenza, okwenza uhlelo lokusebenza lusebenze ngokushesha okukhulu.
I-Payments Mechanism
Intuthuko enkulu imenyezelwe endaweni yokukhokha, yezinhlelo zokusebenza zeselula ezenziwe kusetshenziswa inguqulo ye-Flutter 2.2. Ngesibuyekezo esisha, kwethulwe i-plug-in entsha yezinkokhelo eyakhiwe ngosizo lwethimba le-Google Play. Ngale plug-in ewusizo, onjiniyela bangashumeka izici ukuze bamukele izinkokhelo zezimpahla ezibonakalayo, kuzo zombili izinhlelo zokusebenza ze-Android ne-iOS.
Ngaphandle kwalokho, i-plug-in yokuthenga yangaphakathi nohlelo ekhona kakade ibuyekeziwe ngokuvikeleka okwengeziwe nokubethela kokwenziwayo kwezezimali okuphephile.
Ukuthuthukiswa Kwewebhu
Esikhaleni sokuthuthukiswa kwewebhu, iFlutter 2.2 inezibuyekezo ezithokozisayo. Manje, abathuthukisi bangasebenzisa abasebenzi besevisi ukuze balondoloze isikhashana ngemuva. Lokhu kusho ukuthi izinhlelo zokusebenza ezisuselwe kuwebhu zizoshesha, futhi zibe namandla, zihumushele ekusebenzeni okungcono.
I-Dart Enezici Eziningi
Ikhishwe kuqala ngaphambi kwe-Flutter, i-Dart iwulimi lokuhlela olusekela uhlaka lokuthuthukisa lwe-Flutter lwezinhlelo zokusebenza ze-cross-platform.
Ngenguqulo 2.2, i-Dart ithuthukiselwe kunguqulo 2.13. Ngale nguqulo entsha, i-Dart manje izonweba ukusekelwa nokusebenzisana komdabu. Lokhu kwenziwe kwaba nokwenzeka ngokusekela ama-arrays kanye nezinhlaka ezipakishiwe ku-FFI (isikhombimsebenzisi somsebenzi wangaphandle).
Lesi sibuyekezo sizosiza ukuthuthukisa ukufundeka futhi sivule ingosi yezimo zokuhlenga kabusha.
Usayizi wohlelo lokusebenza
Emzamweni wokwenza izinhlelo zokusebenza zeselula zibe nesisindo esilula futhi zibe ncane kakhulu, i-Flutter 2.2 manje izovumela izinhlelo zokusebenza ze-Android ukuthi zibe nezingxenye ezihlehlisiwe. Ngale ndlela, ama-elementi e-Flutter adingekayo ukuze kusebenze kahle uhlelo lokusebenza angalandwa ngesikhathi sokusebenza, ngakho-ke, asikho isidingo sokulayisha ikhodi eyengeziwe kuhlelo lokusebenza. Ngale ndlela, izinhlelo zokusebenza zizolula ngosayizi manje.
Ekuthuthukisweni kwe-iOS, i-Flutter 2.2 manje ivumela abathuthukisi ukuthi bahlanganise ama-shader, okuzokwenza izithombe ezinyakazayo zibe bushelelezi futhi zingabi namthungo (uma zisetshenziswa isikhathi sokuqala). Ngaphandle kwalokho, amanye amathuluzi amasha engeziwe azovumela abathuthukisi ukuthi bahlaziye ukusetshenziswa kwememori kunoma yiluphi uhlelo lokusebenza, ngaleyo ndlela abanikeze amandla okuqondisa ukusetshenziswa kwememori nokwenza uhlelo lokusebenza lusebenze kangcono.
Unentshisekelo yokuthuthukisa uhlelo lokusebenza olusha olususelwe ku-Flutter noma ufisa ukwenza kabusha izinhlelo zakho zokusebenza zomdabu ezikhona ngamakhono we-cross-platform usebenzisa i-Flutter?
