2 years ago Thanks for reaching out! The problem is that you're assigning a query widget to a list. This fails because the query instance is not a list.
I think you need to take a look at the readme of the package to get an fundamental understanding of how this library works. The Query is a widget and should be handled as such.
Hello,
I am not sure if this is the bug or I should request a feature. I use graphql flutter to retrieve the data (appointments) from my mongodb, so I could display it within the Syncfusion calendar. However I get the error message saying that 'The type 'Query is not a subtype of type 'List' in type cast'.
The code: List appointments = Query( options: QueryOptions(document: gql(_getEvents)), builder: (result, {fetchMore, refetch}) { if (result.isLoading) { return const CircularProgressIndicator(); } else { result.data!["events"]; } throw const Text('Something happened'); }) as List; return _DataSource(appointments); }
The expected behavior: have the query converted to list and get the events displayed.
Device / execution context: iOS simulator
What backend are you trying to use? MongoDB, mongoose, node.js, express
Please advise if there is anything that can be done.
Thank you, Maria
