Ques game in flutter

I have a firebase database which has multiple questions, and use this database in an app. I want a flutter programer to make some games for my app. These games use these questions in the firebase. For example, a game like who want be a millionaire. A record game which record a highest record for students who play this game. Also a game which the player buit his castle of knowledge which mean the player will answer many questions, if the answer is right a part of the castle will be built esle if the answer is wrong a part or more will be taken out until he or she complete the building.
