如何运行Flutter示例代码到鸿蒙平台上
如何运行Flutter示例代码到鸿蒙平台上
大家好，今天我们一起来看一下使用相机调用这个案例，一起来看一下flutter代码运行到鸿蒙平台的效果
首先大家需要下载这个仓库
testcamera
1.下载代码
gitclonegit@gitcode.com:openharmony-tpc/flutter_samples.git2.适配ohos的案例都在ohos目录下

现在这里面就是我们的这些适配了ohos的目录

3.进入testcamera目录
cdtestcamera4.现在就可以直接使用flutter run来测试了。
这个时候会报错

找到对应的文件
5.打开deveco。签名
6.现在就可以尝试了

现在我们就可以对现在的源码继续分享了。
