参数类型'AssetGenImage‘不能分配给参数类型'ImageProvider’
参数类型'AssetGenImage‘不能分配给参数类型'ImageProvider’
提问于 2022-08-15 19:19:29
我正在使用颤振gen软件包来初始化图像。
Widget build(BuildContext context) {
return SafeArea(
child: Scaffold(
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Image(image: Assets.images.logo, height: 64),//error is here
const SizedBox(
height: 32,
),
const SpinKitFadingCube(
color: Solidcolors.primaryColor,
size: 32.0,
)
],
),
),
),
);
}
}这是一个错误：
参数类型'AssetGenImage‘不能分配给参数类型'ImageProvider’
下面是我生成的文件：
import 'package:flutter/widgets.dart';
class $AssetsImagesGen {
const $AssetsImagesGen();
/// File path: assets/images/logo.png
AssetGenImage get logo => const
AssetGenImage('assets/images/logo.png');
}
class Assets {
Assets._();
static const $AssetsImagesGen images =
$AssetsImagesGen();

只需作为Assets.logo.image()使用，它本身就能提供图像。
children: [
Assets.logo.image(height:64),右侧部分将生成。
