React Native - console.error: 'React Native version mismatch

-

I am using EXPO and React Native, the app work running completely fine until it suddenly stopped when I made a new file and even when I deleted it, the error stayed.

I have updated React Native to V0.56.0 but it is still showing the error:

console.error: 'React Native version mismatch.

Javascript version: 0.56.0 Native Version: 0.52.0

Before I updated it was:

Javascript version: 0.54.0 Native Version: 0.52.0

and still causing the same error?

Any ideas on how I fix this and which command I use to update the Native Version?

Go to package.json file inside your project folder

Where you can find code like this 

 "dependencies": {
 .....
  "react-native": "^0.54.0",
  ......

},

change the react-native-version to 0.54 and save file.

Then goto the terminal and redirect to your project folder and hit the command

npm-install

Meaning of `{}` for return expression

-
15 1 I found by accident that the following compiles: #include <string> #include <iostream> class A{ int i{}; std::string s{}; public: A(int _i, const std::string& _s) : i(_i), s(_s) { puts("Called A(int, const std::string)"); } }; A foo(int k, const char* cstr){ return {k, cstr}; // (*) } int main(){ auto a = foo(10, "Hi!"); return 0; } The line of interest is (*). I guess the function foo is equivalent to: A foo(int k, const char* str){ return A(k, cstr); } However, is there a special name for this mechanism in (*)? Or is it just the simple fact that the compiler knows which constructor to call due to the return type? ...

Get current scroll position of ScrollView in React Native

-
Is it possible to get the current scroll position, or the current page of a <ScrollView> component in React Native? So something like: <ScrollView horizontal={true} pagingEnabled={true} onScrollAnimationEnd={() => { // get this scrollview's current page or x/y scroll position }}> this.state.data.map(function(e, i) { <ImageCt key={i}></ImageCt> }) </ScrollView> Try. <ScrollView onScroll={this.handleScroll} /> And then: handleScroll: function(event: Object) { console.log(event.nativeEvent.contentOffset.y); }, Disclaimer: what follows is primarily the result of my own experimentation in React Native 0.50. The ScrollView documentation is currently missing a lot of the information covered below; for instance onScrollEndDrag is completely undocumented. Since everything here relies upon undocumented behaviour, I can unfortunately make no promises that this information will remain correct a ...
