• Broadened SDK constraint to >=2.12.0 <4.0.0 (Flutter >=2.0.0) so the package installs on older null-safe Flutter projects.
• Loosened dependency ranges on sqflite, sqflite_common_ffi and path_provider to >=2.0.0 <3.0.0.
• Added an explicit import 'package:sqflite/sqflite.dart'; so the package still resolves Database, DatabaseFactory and databaseFactory when the lowest allowed sqflite_common_ffi is selected (fixes pub.dev "dependency constraint lower bounds" downgrade analysis).
• Replaced Enum.name (Dart 2.15+) with toString().split('.').last so the library runs on Dart 2.12.

Major maintenance release. The public API is kept backwards-compatible with 1.x — no method renames. Update your pubspec.yaml and you're done.

Requirements

• Minimum SDK Dart >=3.4.0 and Flutter >=3.22.0 (lowered in 2.0.1).

Fixes

• changeDB was using the native sqflite backend on Windows instead of the FFI backend; the platform detection is now consistent with the rest of the library.
• changeDB no longer crashes when the database has never been opened.
• Linux now correctly uses the FFI backend (previously only Windows did).
• getEntityColumnsName<T> was always returning an empty list because a shadowed local variable prevented the result from escaping the transaction.
• validatePath now strips a single trailing separator instead of chopping off two characters.
• deleteFile now returns true when the file did not exist and false on failure, instead of always returning the post-deletion existence state.
• getImageFromDisc no longer throws when the image file cannot be read.
• countElementsOf tolerates NULL results from SQLite and returns 0 instead of throwing.
• Sanitization of WHERE clauses no longer matches identifiers that start with true/false (\btrue\b / \bfalse\b word boundaries).
• cleanAllTablesData now skips sqlite_master and internal tables.

Improvements

• Dependencies updated to their latest stable versions:
  • sqflite: ^2.4.2
  • sqflite_common_ffi: ^2.4.0
  • path_provider: ^2.1.5
  • flutter_lints: ^6.0.0
• Package documentation rewritten in clearer English, with consistent examples.
• Stricter analyzer configuration (strict-casts, strict-inference, strict-raw-types, several extra lint rules).
• Uses Random.secure() for newKey.
• Internal code cleanup (removed dead commented code, tightened types where the public signature is not affected).
