flutter - 我是否需要删除存储在 path_provider.getTemporaryDirectory() 中的图像，因为我将其用作临时占位符？

Question

我正在使用一个名为 path_provider 的 flutter 插件。我必须将图像文件存储在 path_provider.getTemporaryDirectory() 中。存储在此处的图像是自动删除还是我必须明确删除。

Answer 1

来自path_provider的文档

Files in this directory may be cleared at any time. This does not returna new temporary directory. Instead, the caller is responsible for creating(and cleaning up) files or directories within this directory. Thisdirectory is scoped to the calling application.

所以你负责清理，也就是说不会自动清理，而是随时可能清理

编辑

您可以按如下方式清除临时目录:

import 'dart:io';
....
Directory dir = await getTemporaryDirectory();
dir.deleteSync(recursive: true);
dir.create(); // This will create the temporary directory again. So temporary files will only be deleted
