Storing data easily via Storage classes

Storing data to file

class Profile implements Serializable {
    final String name;

    Profile({required this.name});

    @override
    Map<String, dynamic> toMap() {
        return {
            "name": name,
        };
    }
}

class ProfileAdapter implements IAdapter<Profile, Map<String, dynamic>> {
  @override
  Profile convert(Map<String, dynamic> data) {
    return Profile(name: data['name']);
  }
}

class ProfileStoreRepo extends FileStoreRepo<Profile> {
  ProfileStoreRepo({
    super.filename = "profile.txt",
  }) : super(adapter: ProfileAdapter());
}

final storeRepo = ProfileStoreRepo();
final Profile p = await network.fetchProfile();
await storeRepo.save(p);

final storeRepo = ProfileStoreRepo();
final savedProfile = await storeRepo.fetch();
if(savedProfile == null) {
    print("No saved Profile Found");
}

Storing data to Shared Preferences

class Token implements Serializable {
  final String accessToken;
  Token({
    required this.accessToken,
  });

  @override
  Map<String, dynamic> toMap() {
    return {
      "access_token": accessToken,
    };
  }
}

class TokenAdapter implements IAdapter<Token, Map<String, dynamic>> {
  @override
  Token convert(Map<String, dynamic> data) {
    return Token(accessToken: data['access_token']);
  }
}

class TokenStoreRepo extends PrefsStoreRepo<Token> {
  TokenStoreRepo({
    required super.prefs,
    super.key = "@token",
  }) : super(adapter: TokenAdapter());
}

final storeRepo = TokenStoreRepo();
final Token p = await network.login(email, password);
await storeRepo.save(p);

final storeRepo = TokenStoreRepo();
final savedToken = await storeRepo.fetch();
if(savedProfile == null) {
    print("No saved Token Found");
}

Using validators

TextFormField(
    validator: Validator.validateEmpty,
)
