This Error is related to Fabric Crashlytics, not direct RestFul API consumptions.

I'm getting this error when initiating the Fabric Crashlytics on Android Emulator

E/Fabric: Settings request failed.

如何将日期从 转换dd/MM/YYYY为YYYY-MM-dd

示例：转换08/11/2019为2019-11-08

我尝试了以下代码，但得到了

无效的日期格式08/11/2019异常

import 'package:intl/intl.dart';

DateFormat('YYYY-MM-dd').format(DateTime.parse('08.11.2019'));

我有两张可绘制的图片,最初FAB设置为R.drawable.icon1,我想在点击它时将其设置为R.drawable.icon2,并在再点击一次时将其设置回icon1,依此类推. ..

有没有办法做到这一点？
