at first we'll need to create a todo-list

i don't want to reinvent the wheel with this task. so we'll use code that other people created so far.

please take a look at this projects and tell me what we can grab from them.

https://github.com/benawad/react-native-todo
https://github.com/rishabhbhatia/react-native-todo
https://snack.expo.io/rk-rHa2nl

so this task is more about reviewing code of other people, copying parts and creating a first version of project that we'll extend later.
