Please, do not hurry to close this question as duplicate. I have read the official documentation here and so fa I have managed to pass successfully parameters between screens. There is som problem with my current case, and the solution is not obvious for me.
I have two screens. The first is called "Feed" and it belongs to bottom tab navigator. From the "Feed" screen I want to be able to navigate to "Comments" screen which is part of stack navigator.
I am able to successfully navigate between both screens, however, for some reason I am not able to pass any parameters when I navigate from "Feed" to "Comments".
Part of my "Feed" screen where I press "comments" icon:
<TouchableOpacity
onPress={() => {
console.log("passing param id: ", id);
navigation.navigate("Comments", { id: id });
}}
>
<FontAwesome name="comment-o" size={30} color="#0047AB" />
</TouchableOpacity>
What I see on the console:
passing param id: some_id_whic_does_not_matter
I manage to successfully navigate to my "Comments" screen. Part of my "Comments" screen:
const CommentsScreen = (props) => {
console.log("Comments Screen: ");
console.log("comments: ", props);
What I see on the console for the route object:
route": Object {
"key": "Comments-some-key",
"name": "Comments",
"params": undefined,
}
Can you tell me what I am doing wrong?
Where I am currently located on NetworkNavigator
tab, and from there I want to navigate to the Comments
screen.
I still dont see where the issue is?
I think we access params via route
I mean
const CommentsScreen =({route})=>{
const {id} = route.params;
console.log(id);
...}
You can access your passed params via following
const CommentsScreen = (props) => {
console.log("Comments Screen: ");
console.log("comments: ", props.route.params.id);
props.route.params
It contains the object you passed in
navigation.navigation('screenname', {
...this object...
});
you can extract the data by using the same keys.
Example
navigation.navigation('screenname', {
id: '1',
name: 'Adam',
age: 12
});
//Then you can access via
console.log("id: ", props.route.params.id);
console.log("name: ", props.route.params.name);
console.log("age: ", props.route.params.age);
I found the answer to my question here: https://reactnavigation.org/docs/5.x/nesting-navigators#passing-params-to-a-screen-in-a-nested-navigator
So in my case:
navigation.navigate("Root Navigator", {
screen: "Comments",
params: { id: id },
});
