React Native Navigation V2

Olá, estou com dificuldades com a versão 2 da biblioteca, fico preso na splash screen (tela branca). Gostaria de saber o que estou fazendo errado. Segue o código:

package.json

"dependencies": 
    ...
    "react": "16.5.0",
    "react-native": "0.57.0",
    "react-native-navigation": "^2.0.2641",
    ...
  },

app.js

export default () => {
  Navigation.registerComponent('Login', () => Login);
  Navigation.registerComponent('Main', () => Main);

  AsyncStorage.getItem('token')
    .then(token => {
      if(token) {
        return {
          name: 'Main',
          options: {
            topBar: {
              title: {
                text: 'Dashboard'
              }
            }
          }
        };
      }

      return {
        name: 'Login',
        options: {
          topBar: {
            hidden: true,
          },
          statusBar: {
            style: 'dark'
          }
        }
      };
    })
    .then(screen => {
      Navigation.events().registerAppLaunchedListener(() => {
        Navigation.setRoot({
          root: {
            stack: {
              children: [
                {
                  component: screen
                }
              ],
            }
          }
        });
      });
    });
}

Login.js

AsyncStorage.setItem('token', token);
AsyncStorage.setItem('user', this.state.user);

this.props.navigator.setStackRoot(this.props.componentId, {
    component: {
        name: 'Main',
        options: {
          topBar: {
            title: {
              text: 'Dashboard'
            }
          }
        }
    }
})

Main.js

this.props.navigator.push(this.props.componentId, {
      component: {
        name: 'Detail',
        options: {
          topBar: {
            title: {
              text: 'Details'
            }
          }
        }
      }
    })
