🍧Cache Utilities #
🌟CacheManagerUtils.conditionalCache({key, valueType, actionIfNull, actionIfNotNull})

Conditional builder based on the value of cache. actionIfNull & actionIfNotNull are dynamic arguments used for Navigation through views, Rendering UI, Debugging values etc. The valueType refers to the datatype of cache (StringValue, BoolValue, IntValue, DoubleValue)

🌟CacheManagerUtils.cacheTextBuilder(textStyle, cacheKey})

TextBuilder for the cached value. cacheKey is the key used to address the cache. The builder will return 'Invalid cache' if no cache is missing. Use textStyle to style the value of the cache.

👀Read cache #
🌟ReadCache.getJson(key) : Get JSON stored as cache.
🌟ReadCache.getString(key) : Get string stored as cache.
🌟ReadCache.getBool(key) : Get boolean stored as cache.
🌟ReadCache.getInt(key) : Get integer stored as cache.
🌟ReadCache.getDouble(key) : Get double stored as cache.
🖊Write cache #
🌟WriteCache.setJson(key,value) : Set JSON as cache.
🌟WriteCache.setString(key,value) : Set a string as cache.
🌟WriteCache.setInt(key,value) : Set an integer as cache.
🌟WriteCache.setBool(key,value) : Set a boolean as cache.
🌟WriteCache.setDouble(key,value) : Set a double as cache.
🌟WriteCache.setListString(key,value) : Set a List of string as cache.
❌Delete cache #
🌟DeleteCache.deleteKey(key,[takeAction]) : Delete the cache and perform an action when cache is deleted(Optional).
Example : Login flow with caching userID #

//Attached function in a login view
Future<String?> login({
required BuildContext context,
required String email,
required String password,
}) async {
try {
var userId = await _authenticationService.login(
context: context, email: email, password: password);
await WriteCache.setString(key: "cache", value: userId!);
} catch (e) {
print(e); //Do something if error occurs
}
}

//Splash view
import 'dart:async';
import 'package:cache_manager/cache_manager.dart';
import 'package:flutter/material.dart';

class SplashView extends StatefulWidget {
@override
_SplashViewState createState() => _SplashViewState();
}

class _SplashViewState extends State<SplashView> {
Future initiateCache() async {
return CacheManagerUtils.conditionalCache(
key: "cache",
valueType: ValueType.StringValue,
actionIfNull: () {
Navigator.of(context).pushNamed(AppRoutes.LoginRoute);
},
actionIfNotNull: () {
Navigator.of(context).pushNamed(AppRoutes.HomeRoute);
});
}

@override
void initState() {
Timer(Duration(seconds: 1), initiateCache);
super.initState();
}

@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Text("demo app"),
),
);
}
}

//Home view
import 'package:cache_manager/core/cache_manager_utils.dart';
import 'package:cache_manager/core/delete_cache_service.dart';
import 'package:flutter/material.dart';

class HomeView extends StatefulWidget {
@override
_HomeViewState createState() => _HomeViewState();
}

class _HomeViewState extends State<HomeView> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: CacheManagerUtils.cacheTextBuilder(
textStyle: TextStyle(color: Colors.white), cacheKey: "cache"),
),
floatingActionButton: FloatingActionButton(
onPressed: () {
DeleteCache.deleteKey(
"cache", Navigator.of(context).pushNamed(AppRoutes.LoginRoute));
},
),
);
