flutter_file_picker 0.0.3

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 3 optional parameters to help pick only specific document type:

  • 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.

    More info: https://developer.apple.com/library/archive/qa/qa1587/_index.html

  • List<String> allowedFileExtensions (used both in iOS and in Android)

    List of file extensions that picked file should have. If list is null or empty - picked document extension will not be checked.

  • List<String> allowedMimeTypes (used only in Android)

    Only files with provided MIME types will be shown in document picker. If list is null or empty - */* MIME type will be used.

  • List<String> invalidFileNameSymbols (used both in iOS and in Android)

    List symbols that will be sanitized to "_" in the selected document name. I.e. Google Drive allows symbol '/' in the document name, but this symbol is not allowed in file name that will be saved locally.

    Default list: ['/'].

    Example: file name 'Report_2018/12/08.txt' will be replaced to 'Report_2018_12_08.txt'

Example #

//Without parameters:
final path = await FlutterDocumentPicker.openDocument();

//With parameters:
FlutterDocumentPickerParams params = FlutterDocumentPickerParams(      
  allowedFileExtensions: ['mwfbak'],
  allowedUtiTypes: ['com.sidlatau.example.mwfbak'],
  allowedMimeTypes: ['application/*'],
  invalidFileNameSymbols: ['/'],

final path = await FlutterDocumentPicker.openDocument(params: params);
