A <LinearGradient> element for react-native
npm install react-native-linear-gradient-spireA component for react-native, as seen in
react-native-login.
Version 2.0 supports react-native >= 0.40.0
You can try linking the project automatically:
$ react-native link
or do it manually as described below:
- Run npm install react-native-linear-gradient-spire --save
Then either:
#####Cocoapods
add the following line to your Podfile:
``sh`
pod 'React', :path => '../node_modules/react-native'
pod 'BVLinearGradient', :path => '../node_modules/react-native-linear-gradient-spire'
or:
#####Manually
1. Open your project in XCode, right click on Libraries and click Add
Files to "Your Project Name" Look under node_modules/react-native-linear-gradient-spire and add BVLinearGradient.xcodeproj. (Screenshot).libBVLinearGradient.a
2. Add to Build Phases -> Link Binary With LibrariesBVLinearGradient.xcodeproj
(Screenshot).
3. Click on in Libraries and go the Build
Settings tab. Double click the text to the right of Header Search
Paths and verify that it has $(SRCROOT)/../react-native/React - if itBVLinearGradient
isn't, then add it. This is so XCode is able to find the headers that
the source files are referring to by pointing to thereact-native
header files installed within the node_modules
directory. (Screenshot).
Then:
- Whenever you want to use it within React code now you can: import LinearGradient from 'react-native-linear-gradient-spire';
If you're having trouble, you can point your package.json at github to see if the issue has been fixed. Simply change the dependency
"react-native-linear-gradient": "react-native-community/react-native-linear-gradient",
to get the data right from github instead of npm and then npm install
For instance the podspec file does not contain the right data (author attributes etc..) in npm while it does in the github repo.
#### Android
1. in android/settings.gradle`
`
...
include ':react-native-linear-gradient'
project(':react-native-linear-gradient').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-linear-gradient-spire/android')
2. in android/app/build.gradle add:`
`
dependencies {
...
compile project(':react-native-linear-gradient-spire')
}
3. and finally, in android/src/main/java/com/{YOUR_APP_NAME}/MainActivity.java for react-native < 0.29,android/src/main/java/com/{YOUR_APP_NAME}/MainApplication.java
or for react-native >= 0.29 add:`
java`
//...
import com.BV.LinearGradient.LinearGradientPackage; // <--- This!
//...
@Override
protected List
return Arrays.
new MainReactPackage(),
new LinearGradientPackage() // <---- and This!
);
}
The following code will produce something like this:
`javascript
import LinearGradient from 'react-native-linear-gradient';
// Within your render function

// Later on in your styles..
var styles = StyleSheet.create({
linearGradient: {
flex: 1,
paddingLeft: 15,
paddingRight: 15,
borderRadius: 5
},
buttonText: {
fontSize: 18,
fontFamily: 'Gill Sans',
textAlign: 'center',
margin: 10,
color: '#ffffff',
backgroundColor: 'transparent',
},
});
`
You can also use start and end points, as well as specify the locations
for the gradient color changes with the start, end and locations
props:
`javascript`
locations={[0,0.5,0.6]}
colors={['#4c669f', '#3b5998', '#192f6a']}
style={styles.linearGradient}>
