API Cache Manager is a Utility package built with Flutter SDK and
SQLite Package. This package will help to make your Rest API store in
the local db for offline access.
import
import 'package:api_cache_manager/api_cache_manager.dart';
import 'package:api_cache_manager/models/cache_db_model.dart';
import 'package:api_cache_manager/utils/cache_db_helper.dart';
This will provide all cached data
List<Map<String,dynamic>> list = await APICacheDBHelper.query(APICacheDBModel.table);
OR
List<Map<String,dynamic>> list =await APICacheDBHelper.rawQuery("select * from ${APICacheDBModel.table}");
This will create dummy data and save in cache and return all data from the cache
Future<List<Map<String, dynamic>>> fetchapiCach() async {
// await APICacheDBHelper.deleteAll(APICacheDBModel.table);
var lists = new List<int>.generate(10, (i) => i + 1);
lists.forEach((element) async {
var cacheData2 = await APICacheManager().addCacheData(new APICacheDBModel(
syncData: '{"name":"lava$element"}',
key: "$element",
));
});
List<Map<String,dynamic>> list = await APICacheDBHelper.query(APICacheDBModel.table);
// await APICacheDBHelper.rawQuery("select * from ${APICacheDBModel.table}");
return list;
}
SampleCode
import 'package:api_cache_manager/api_cache_manager.dart';
import 'package:api_cache_manager/models/cache_db_model.dart';
import 'package:api_cache_manager/utils/cache_db_helper.dart';
import 'package:flutter/material.dart';
void main() {
// fetchapiCach();
runApp(const MyApp());
}
Future<List<Map<String, dynamic>>> fetchapiCach() async {
// await APICacheDBHelper.deleteAll(APICacheDBModel.table);
var lists = new List<int>.generate(10, (i) => i + 1);
lists.forEach((element) async {
var cacheData2 = await APICacheManager().addCacheData(new APICacheDBModel(
syncData: '{"name":"lava$element"}',
key: "$element",
));
});
List<Map<String,dynamic>> list = await APICacheDBHelper.query(APICacheDBModel.table);
// await APICacheDBHelper.rawQuery("select * from ${APICacheDBModel.table}");
// print(list);
list.forEach((element) {
print(element);
});
return list;
}
