CodePudding user response：

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;
