I don't know exactly what happened when I'm using the nanoid package in react native it's shown some kind of below error. I'm not sure about it.

I hope someone help from this community.

Issue resolved

I have resolved this issue by using the following functions.

So I think in the nanoid used crypto module so in react-native it doesn't exist.

For that, we need to use a nanoid/non-secure module. Below I have also used customAlphabet method.

Finally it works. :)

react-native-map-clustering: Slow UI render / transition on selection change

Asked 2021-Mar-12 at 17:10

I'm a little lost with a current issue in my app when rendering a checklist. react-devtools show no performance issues, however there's a visible delay / kind of fading render appearing on the UI when selecting the Google Maps item from the list. Here are two animated screenshots with different speeds (x1.0 and x0.3):

react-devtools shows this for rendering the changed selection:

Update: Actually the issue is that if your clustered map is animation enabled using the animationEnabled prop here, any following UI change is animated on iOS, see here.

I now reverted my original change (see below) and simply set the animationEnabled prop to false.

Initial answer:

Alright, found it (my fault :)) As you can see from the attached package.json file I'm using react-native-maps and react-navigation. As the screen rendering the map was not dismissed by react-navigationwhen navigating to the settings shown in the screenshots and changing the settings affects which map is rendered, changing the settings and the following update to the redux store trigger the hooks of my map component, thus re-rendering the screen and slowing down the app.

I addressed this issue now by using react-navigation event listeners and unmounting the map screen whenever it loses focus.

React Native - Google Fit API can't get steps

Asked 2020-Sep-02 at 07:06

I use react-native-google-fit package to get the steps data about the user. In my case this package works fine in some devices but in some others cant get any data or response from the google-fit API.

I cant understand what is the problem, as I know step recording api of the google-fit is not implemented in default as it is in IOS(health-kit). I implemented bugnsag to track the steps and the process stucks when I call google-fit API to get step samples. No error or exception thrown it just feels like hanging.

If anyone have some idea or solution about it I would be very happy to hear.

Well I solved the issue.. Still its very weird issue but, first of course its my fault to not check documentation again. Seconds its bad documentation and naming.. Like how you can write READ_WRITE and it can only mean WRITE?

Unable to resolve module util from node_modules\uuidv4\build\lib\uuidv4.js: util could not be found within the project

Looks like the issue is with the npm cache. Try the following solution:

Run the command: npm cache verify

If you get errors then run: npm cache clear --force

Right Click on C: > Properties > Tools Tab.

Select Check or Check-now under Error Checking menu.

Reboot your PC after the process is completed.
