5// <Button /> does not accept a style other then color but thats that.
6// if you want a custom button you need to use <Pressable /> or any thing else-
7//- the thing you want to press just need to have onPress on it.

9<Text onPress={() => console.log("you pressed a text")}>click me</Text>
10
11
12<Text onPress={() => function()}>click me</Text>
13//function is your own function.
14
15//if you want the thing you press on to chance so the user can see that they puched it.
16//you can use the Touchable component.
17//here we are using the TouchableOpactity where the opacity change when it is pressed.
18<TouchableOpacity onPress={() => console.log("you pressed a touchableOpacty component")}>
19<Text>click me</Text>
20</TouchableOpacity>
21//the best option might be <TouchableOpacity></TouchableOpacity> to make your own button
22
23<Pressable onPress={() => console.log("you pressed me")}><Text>click me</Text></Pressable>
24//as you can see you can use a lot of thing as a button but if you usethese
25//you can style them as you want.
26//rember you need to import Touchable and Pressable before you can use em.
