when add ! The operator '[]' isn't defined for the type 'Object'
you can just add the type of the future you are using like this one
//this one wont work
body: FutureBuilder(

builder: (ctx, snapShot) {

return Center(child: CircularProgressIndicator());

body: FutureBuilder<dynamic>(
future:getDataFromJason(),
builder: (ctx, snapShot) {
if(snapShot.connectionState==ConnectionState.waiting){
return Center(child: CircularProgressIndicator());
}
else{
