I had a factory method for converting json into an object which accepted Map<String, dynamic> json as argument from sqlite database like below
factory Lecturer.fromJson(Map<String, dynamic> json)=>Lecturer(
name:json['name'],
email: json['email'],
);
the data is returned in a future builder and access like this
FutureBuilder(
future: DB.getLecturer(),
builder: (_,lect){
if(!lect.hasData){
return CircularProgressIndicator();
}
Lecturer l=Lecturer.fromJson(lect.data[0]);
}),
but after upgrading my flutter to a newer version I realized the return type for SQL queries is no longer Map<String, dynamic> but rather Map<String, Object?> , I now get the error below from a code that was working perfectly just last week. Please any help will be appreciated
Error: The operator '[]' isn't defined for the class 'Object?'
