flutter - 如何检查和删除flf中所有现有的sqflite数据库？(How to check and delete all existing db of sqflite in flutter?)

Question

As I am new to flutter, I have created new DB whenever I have faced an issue, But now I need to remove other unused DB's.

(由于我不熟悉该问题，因此每遇到一个问题就创建一个新的数据库，但是现在我需要删除其他未使用的数据库。)

How can I check existing DB and delete them except currently using?

(除了当前使用的数据库外，如何检查现有数据库并删除它们？)

//final demoDb = 'demoDb1.db';
//final demoDb = 'demoDb2.db';
//final demoDb = 'demoDb3.db';
//final demoDb = 'demoDb4.db';
final demoDb = 'demoDb5.db'; //Currently using this one

createDatabase() async {
    Directory documentsDirectory = await getApplicationDocumentsDirectory();
    String path = join(documentsDirectory.path, demoDb);

    var database = await openDatabase(path,
        version: 1, onCreate: initDB, onUpgrade: onUpgrade);
    return database;
  }

Thanks in advance.

(提前致谢。)
