Text(snapshot.data![index].address!.city.toString()), sir what is this ! sign used for for null safety we use string?

[@thetechbrotherss]

! sign means data cannot be null

[@MuhammadASIF-wu5sk]

It shows te following error. When i use Usermodel. Fromjson(i) ; In for loop. Error. The argument type

[@thetechbrotherss]

Its not error it’s pretty much clear your model has different variables go and change it to dynamic

[@shahabuddin-pc8jr]

i also facing this ,,how u resolved this?

[@freelancermunim-eq4wm]

Sir I have a question...why did we use snapshot.data[index].data.title.toString() whereas we have used post[index].title.toString() for the same API in the previous video? and Thank you for the tutorial...respect from Bangladesh

[@thetechbrotherss]

To be honest i don't remember now, i created this video long ago, but i must have explain this in the whole playlist

[@syedshabbarraza6384]

I think both methods are identical and working same the difference only was previously we was first storing data to list them fetching and displaying directly from list But now we are just changed the path of fetching It just thing that I understand may be right may be wrong 🤷

[@areebafarooq2694]

if we have a json response start with curly brackets { response:1, code: 200, data: { "id":1, "name": areeba}} like this ... still would this be consider as a list???

[@thetechbrotherss]

ni array [ ] in symbol sy represent hoti ha r array he list hoti ha, please ma phr recommend krun ga ap basic json structure wali video dekhain r usko smhhain warna ap simple c api par bhi struggle karin ge
