Methods

//this returns object
this.console.log(JSON.stringify(this.$AppTheme.theme,null,2));



//this returns object
let themeName = 'light' 
this.console.log(JSON.stringify(this.$AppTheme.theme[themeName],null,2))
/*result 
 {
  textColor:'#ededed,
  backgroundColor:'#101010'
 }
 */
 
 
 
// we can still go further
let themeName = 'light' 
this.console.log(JSON.stringify(this.$AppTheme.theme[themeName].textColor,null,2))
//returns '#ededed' 

this.console.log(this.$AppTheme.textColor)
//returns currently selected theme textColor '#ededed' 





/*This will be called once Theme Plugin has been initialized
This can be used in your App.vue or default.vue file or any other component
you wish to use it in
*/
 this.$AppTheme.onReady((themeExistInDeviceDB)=>{
 if(themeExistInDeviceDB){
    this.$AppTheme.setThemeFromStorage();//this is to set theme from db
   }
 });
 




//This will be called when New Theme has been Selected
this.$AppTheme.onThemeChanged((themeName,themeOptions)=>{
...
//do what ever you want with the results
})





this.$AppTheme.addTheme({textColor:'red',backgroundColor:'gold'},"splash",true);
//this.$AppTheme.addTheme({options},themeName,activate)

/*
*options = "object" or "json-string" @required
*themeName = "String" intended name for theme @optional default  is "default"
*activate = boolean --activate theme or not
*/




this.$AppTheme.saveTheme(); //save theme to db 

//this can also be changed like this
this.$AppTheme.addTheme(...).saveTheme();



this.$AppTheme.activateTheme(themeName);
//where themeName is a `String` which is already contained in the themeOptions





this.$AppTheme.getTheme(themeName,array);
//returns object of themeOptions

//themeName = name of theme to get options from @required
array = themeoptions to be gotten like ['textColor','backgroundColor'] @optional

///generally data can be accessed like this
this.$AppTheme.getTheme('splash',['textColor']).texColor 
//result 'red'

Points to Note

1. camel case textColor are changed to kebal case text-color only for css variables
2. css variables are dynamic and should be accessed like this var(--text-color)
3. Try as much as possible to name your theme options with camel case textColor, accentColor, backgroundColor
4. css variables acess only the currently selected theme
