Where-Clause Not Applied in Release Builds Using Backendless with Flutter

Flutter
1

Hello everyone,

I’m experiencing an issue with Backendless in my Flutter app, specifically related to the whereClause in data retrieval. The problem occurs only in release builds; find(queryBuilder) call is fetching all records regardless of the specified whereClause. This behavior contrasts with the debug mode, where the whereClause works as expected and filters the records correctly.

Environment: Flutter: [3.3.9]
Backendless SDK Version: [7.3.7]
Affected Platform: [iOS and Android]

How to map class to table name in the new version?
I was using

Backendless.data.mapTableToClass(“MyTableName”, MyCustomType);

Hello, @Marah.

In versions before to 8.0.0, flutter used iOS and Android SDKs. Reflection worked a little differently there. Now you need to add a named constructor fromJson to the class:

Map myMap = {"Users": [

  {"Name": "Mark", "Email": "mark@email"},


  {"Name": "Rick", "Email": "rick@email"},
]
};

@reflector
class MyData {
  String name;
  String email;

  MyData.fromJson(Map json){
    this.name = json["Name"];
    this.email = json ["Email"];
  }
}

Regards, Nikita.
