Insert provider for SQLiteObject ionic 3 - sqlite

Question

I'm working on a project on ionic 3 angular 4. I have to connect to a database and do other things...
So I have a page (.ts .html .scss .module.ts), a provider where I use sql. So my problem is this, I have this error :
core.es5.js:1084
ERROR Error: Uncaught (in promise): Error: No provider for SQLiteObject!
Error: No provider for SQLiteObject!
So in module.ts I added in provider flag i put SQLiteObject. But now I get this new error :
compiler.es5.js:1540 Uncaught Error: Can't resolve all parameters for SQLiteObject: (?).
Also if I put SQLite it wants always the SQLiteObject provider.Anyway I never use SQLite just SQLiteObject
import { SQLiteObject } from '#ionic-native/sqlite';
I google and I found that SQLiteObject is not a provider but just an interface.
So? Any idea? I can put code but is long, if you have some idea please comment.

You need to add its class in providers in your app.module.ts file as:
import { SQLiteObject } from '#ionic-native/sqlite';
#NgModule({
declarations: [
MyApp
],
imports: [
//
],
bootstrap: [IonicApp],
entryComponents: [
MyApp
],
providers: [{provide: ErrorHandler, useClass: IonicErrorHandler}, SQLiteObject]
})
export class AppModule {}

You're right SQLiteObject isn't a Provider but you're trying to import it as one. It is a class Object used by the SQLite Provider so you can save the object from your constructor and then use it as this.db from there. FYI: remove the import { SQLiteObject } statement.
private db: SQLiteObject;
constructor(private sqlite: SQLite)
{
this.sqlite.create({
name: 'data.db',
location: 'default'
})
.then((db: SQLiteObject) => {
this.db = db; //set the object to your own var
db.executeSql("CREATE TABLE IF NOT EXISTS ...", {});
});
}
