正在删除flutter中的多个文件

Question

在ApplicationDiretory中，我创建了finalImage_｛$DateTime.Now((｝文件，我需要删除它们。我需要删除以名称finalImage_*开头的文件，这些文件存在于tempDirectory、中

Below is the snippet which deletes all files    
final cacheDir = await getTemporaryDirectory();

这样尝试：

final cacheDir = await getTemporaryDirectory();
if (cacheDir.existsSync()) {
cacheDir.list(recursive: false).forEach((file) {
String fileName = file.path.split('/').last;
if (fileName.contains("finalImage_")) file.deleteSync(recursive: true);
});
}
