flutter_document_picker

Allows user pick a document. Picked document is copied to app temporary directory. Optionally allows pick document with specific extension only.

When file is picked its extension is checked using allowedFileExtensions parameter. Then file is copied to app temp directory. Copied file path is returned as result. If picked file extension is not in allowedFileExtensions list then extension_mismatch error is returned.

In Android Intent.ACTION_OPEN_DOCUMENT is used. This intent is supported only from Android 19 (KitKat) SDK version. So this plugin can be used only if app minSdkVersion is 19 or more.

In iOS UIDocumentPickerViewController is used. Files can be filtered by list of UTI types using allowedUtiTypes parameter. Picked file path is returned as result.

Params

Plugin has two optional parameters to pick only specific document type: allowedUtiTypes and allowedFileExtensions.

• List<String> allowedUtiTypes (used only in iOS)

  In iOS Uniform Type Identifiers is used to check document types. If list is null or empty "public.data" document type will be provided. Only documents with provided UTI types will be enabled in iOS document picker.
