-**Note:** NativeBase changes a lot and is in constant mutation. We usually merge multiple PRs per day, so sometimes when we are done reviewing, your code might not work with the latest `v3-dev` branch anymore. To prevent this, before you make any changes after your code has been reviewed, you should always rebase the latest changes from the `v3-dev` branch.
