backupDatabase method

Future<File> backupDatabase(String backupPath)

Backs up the current SQLite database to a specified file path.

This method creates a copy of the existing database file at the given backupPath. If a file already exists at backupPath, it will be overwritten.

Usage:

String backupPath = '/path/to/backup/my_database_backup.db';
await backupDatabase(backupPath);

Throws an exception if the backup operation fails, such as due to permission issues or an invalid path.

Implementation

Future<File> backupDatabase(String backupPath) async {
  // Retrieve the current database file path
  var dbPath = path; // Implement this to return the path of your database

  // Create a File object for the database file and the backup location
  final databaseFile = File(dbPath);
  final backupFile = File(backupPath);

  // Check if the database file exists before proceeding
  if (await databaseFile.exists()) {
    // Create a backup by copying the database file
    await databaseFile.copy(backupPath);
    return backupFile;
  } else {
    throw Exception("Database file does not exist at $dbPath");
  }
}
