  print('Bianca record: ${id}');

id = await db.put('parrots', {'name': 'Darko', 'age': 8});
print('Darko record: ${id}');

final q = db.createQuery('/[age > :age]', 'parrots');
await for (final doc in q.setInt('age', 3).execute()) {
  print('Found ${doc}');
}

await db.close();

iOS notes

In order to build app with this binding you have to add the following code into application Podfile:

pre_install do |installer|
  # workaround for https://github.com/CocoaPods/CocoaPods/issues/3289
  Pod::Installer::Xcode::TargetValidator.send(:define_method, :verify_no_static_framework_transitive_dependencies) {}
end

Android notes

For release builds you have to setup proguard rules as follows:

build.gradle

    buildTypes {
      ...
        release {
            ...
            minifyEnabled true
            useProguard true
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        }
    }

proguard-rules.pro
