flutter 预载入 flr 文件 – Records And Memorys

import 'package:flare_flutter/flare_cache.dart';
import 'package:flare_flutter/provider/asset_flare.dart';
import 'package:flutter/services.dart' show rootBundle;

  final _assetsToWarmup = [
    AssetFlare(bundle: rootBundle, name: "assets/homeimages/Scanutt_MainStatus_V001.flr"),
    AssetFlare(bundle: rootBundle, name: "assets/toyimages/Scanutt_Play_V001.flr"),
    AssetFlare(bundle: rootBundle, name: "assets/bathimages/Scanutt_Wash_V1.flr"),
    AssetFlare(bundle: rootBundle, name: "assets/foodimages/Scanutt_EatDrink_V001.flr"),
  ];

  Future<void> warmupFlare() async {
    for (final asset in _assetsToWarmup) {
      await cachedActor(asset);
    }
  }


    FlareCache.doesPrune = false;
    // Warm the cache up.
    await warmupFlare();


---------  以上是预载入部分 ，  如果要使用预载入的flr文件 ，如下 ： 


import 'package:flare_flutter/flare_actor.dart';
import 'home_flr_controller.dart';
import 'package:flare_flutter/flare_cache_builder.dart';
import 'package:flare_flutter/provider/asset_flare.dart';
import 'package:flutter/services.dart' show rootBundle;

                      visible: normalFlrVisible,
                      child: 
                      // FlareActor(
                      //   "assets/homeimages/Scanutt_MainStatus_V001.flr",
                      //   controller: _normalController,
                      //   animation: "Blink",
