Hello,
I am trying to use nativestorage (https://github.com/TheCocoaProject/cordova-plugin-nativestorage) in my application.
All is fine, and I can build the application.
In my app.components.ts I have this
this.setRootPage();
at the end of the this.platform.ready().then(()
Which inturn calls the function
setRootPage() {
//intro skip if value is set
this.nativeStorage.getItem("intro").then((intro) => {
if (intro) {
this.rootPage = Category1Page;
} else {
this.rootPage = IntroPage;
}
});
}
I end up with an error when running the application Error: Uncaught (in promise): [object Object] on both IOS simulator as well as browser using ionic cordova run browser
Your help is great appreciated
