Roadmap

I have moved the roadmap of this library to this trello board so that it can be easier to add more things and like that it doesn’t create issues in GitHub if I need to create a ticket

Roadmap Trello Board

Development

In other to start watch mode and develop the library with the examples project (described above), you need to have installed the following npm packages:

npm -g json
npm -g wml

And have the library and examples project in the same root folder, example:

root
- react-native-nested-listview
- react-native-nested-listview-examples

After the previous steps you can then run the following command:

yarn start-watch

and then you can start the examples app as usual:

yarn ios or yarn android

When you finish with watch mode remember to stop it to get back to normal like this:

yarn stop-watch
