I'm building an app in React native, and basically, I need a modal(which will have the same content every time) to be available globally (in all components of app), so that I can be able to open it from anywhere in my app.
Obviously copy/pasting the same modal in all the components is not a good solution
Right now I'm having tons of trouble implementing it, so I would like to know what would be the best way to accomplish something like that
Use a Navigator and place your modal below it. Make it visible only when the state changes. The state can be changed from each component inside the Navigator via props.navigator.

I would like to know if it's possible to change the bottom tab icon dynamically, I mean, I'm interested to change one of the tab icons when an event occurs...
I have read the documentation but couldn't find any related info about it...
The only solution that I can think of is using a global store variable to control it when it's defined in the bottom tab navigation, using a solution similar to what react-navigation docs proposes here.
I would also think of using a global state management API such as Context API (https://reactjs.org/docs/context.html#dynamic-context), redux (https://redux.js.org/tutorials/quick-start), recoil (https://recoiljs.org/docs/introduction/installation/), etc.
and then set the global state variable on event handler, as well as in the ternary operator in the react-navigation example you provided (in the place
of "focused")
I am using react-native-collapsible for a project. Everything working well but I would like the user to be able to close the collapsible by clicking anywhere on the screen when it is opened. On a desktop it would be easy with a !event.target match but since I am new to React Native (expo) I am a bit out of solution.
Thanks a lot, I pasted no code because I am currently using the Lorem example from the lib so won't be much useful.
You can Make one useState variable and pass it into the property of
collapsed={Your useState Veriable} react-native-collapsible .
also make all the Design wrap into TouchableOpacity and it's onPress event to make it true.
I want to achieve this in react-native,
Is there a component that have this tab switching animation with also capability off adding an icon next to tabName if possible.
P.S: I found a component react-native-material-tabs but without the ability to an icon. Also found components that requires container component, where I just need one for tabs for my use case.
I'm trying to build a React Native app and would like to implement a component just like in Quora where upon clicking the question, the component expands and shows the remaining details (text/images of the question).
I tried using react-native-panel from https://github.com/dwicao/react-native-panel#readme, but it can only handle text in the panel before expanding. I'd like to implement a panel that has an image in it even before I press on the panel to expand. Would love it if anyone could refer me to any npm packages that use components to achieve this. Thank you!
Use this tutorial https://blog.theodo.com/2020/06/build-accordion-list-react-native/. Stick the desired image somewhere there in the code.
I am using react-native, nested react-navigation, SectionLists, ActionSheet, etc and I am having hard times setting up a decent way of refreshing components / screens. As I have a few different cases, I have also tried different approaches with no luck.
Examples:
- Sending a callback function as a param in the navigator when transitioning from one screen to another for state change.
- Assigning AsyncStorage.getItem straight to a state variable (e.g: used on a ListView) and expect it to refresh.
I've seen many questions in the react-navigation git repo (mainly on how to refresh a screen), and recent suggestion to the project on the best approach for future releases, that got me asking if this is something that is in place already.
I can say though, that I've successfully used redux to check the connection state (NetInfo), that although I couldn't yet port the same idea to a different schenario, I think that it is my best approach.
At the moment I have one schenario, that if solved, I believe will answer a few questions I have. For example:
I have a list of news in my Home screen and a few options in my Drawer navigator that I would like to, when clicked, to sort the Home list, without having to call navigate('screen_name') as I would like to, to still keep the Drawer opened after clicked.
What would be the best approach for this ?
Thanks in advance!
One approach you could follow is:
On click on a DrawerNavigator item, you can dispatch an action which would intern change the state by a value. Eg: filterBy: . This store value can be passed as a prop to your home screen, which would intern contain a logic to filter based on that value.
I havent worked with DrawerNavigator but i feel onPress on each item in drawer navigation can be prevented and a action can be invoked at the same place.
