pick_or_save 2.1.2

A Flutter file picking and saving package that enables you to pick or save a single file and multiple files.

Word from creator

Hello👋, This package is comletely compatible with flutter and it also provides option to disable copying of file in cache when picking and provide Android Uri of picked file to work with which offer some real benifits such as getting original file metadata, filtering files before caching or caching them anytime later using Uri.

Yes, without a doubt, giving a free 👍 or ⭐ will encourage me to keep working on this plugin.

Package description

A Flutter file picking and saving package that enables you to pick or save a single file and multiple files.

Note: Although .

Features

• Works on Android 5.0 (API level 21) or later.
• Pick single file, multiple files with certain extensions or mime types.
• Supports photo picker on supported deveices.
• Get meta data like name, size and last modified from from android uri or file path.
• Saves single file while allowing user to choose location and name.
• Saves multiple file while allowing user to choose location or directory for saving all files.
• Saves file from either file path or file data(Uint8List).
• Could limit picking a file to the local device only.
• Get cached file path from android uri or file path.

Note: If you are getting errors in you IDE after updating this plugin to newer version and the error contains works like Redeclaration, Conflicting declarations, Overload resolution ambiguity then to fix that you probably need to remove the older version of plugin from pub cache C:\Users\username\AppData\Local\Pub\Cache\hosted\pub.dev\older_version or simply run flutter clean.

Getting started

• In pubspec.yaml, add this dependency:

pick_or_save: 

• Add this package to your project:

import 'package:pick_or_save/pick_or_save.dart';

Basic Usage

Note: To try the demos shown in below gifs run the example included in this plugin.

Note: For most below examples we set getCachedFilePath = false to get uri path instead of absolute file path from picker. A Uri path can only be used in android native code. By default getCachedFilePath = true which will provide cached file path from picker.

Picking

Picking single file	Picking multiple files

Picking single file and getting uri

List<String>? result = await PickOrSave().filePicker(
  params: FilePickerParams(getCachedFilePath = false),
);
String filePath = result[0];

Picking single file and getting cache path

List<String>? result = await PickOrSave().filePicker(
  params: FilePickerParams(getCachedFilePath = true),
);
String filePath = result[0];

Picking multiple files

List<String>? filesPaths = await PickOrSave().filePicker(
  params: FilePickerParams(getCachedFilePath = false, enableMultipleSelection: true),
);

Resticting picking files to certain mime types

List<String>? filesPaths = await PickOrSave().filePicker(
  params: FilePickerParams(getCachedFilePath = false, mimeTypesFilter: ["image/*", "application/pdf"]),
);

Resticting picking files to certain extensions

List<String>? filesPaths = await PickOrSave().filePicker(
  params: FilePickerParams(getCachedFilePath = false, allowedExtensions: [".txt", ".png"]),
);

Note: This plugin automatically tries to convert the extensions to their respective mime types if supported so that only those become selectable but that may fail if it fails to convert them. Still if a user manages to select other extension files then this plugin automatically discards those other extension files from selection.

Photo Picker

List<String>? filesPaths = await PickOrSave().filePicker(
  params: FilePickerParams(getCachedFilePath = false, pickerType: PickerType.photo, mimeTypesFilter: ["*/*"]),
);

Note: This will show new photo picker only on supported android devices and for unsupported android devices it will show default picker. And it always needs mime type and only first mime type in mimeTypesFilter list is used. So if you want to filter multiple types of files then make sure to provide allowedExtensions as that automatically discards other extension files from selection if selected by user.

Photo picker on supported devices	Photo picker on unsupported devices

Saving

Saving single file from file path

List<String>? result = await PickOrSave().fileSaver(
  params: FileSaverParams(
    saveFiles: [
      SaveFileInfo(
          filePath: filePath,
          fileName: "File.png")
    ],
  )
);
String savedFilePath = result[0];

Saving multiple files from file path

List<String>? result = await PickOrSave().fileSaver(
  params: FileSaverParams(
    saveFiles: [
      SaveFileInfo(
          filePath: filePath,
          fileName: "File 1.png"),
      SaveFileInfo(
          filePath: filePath,
          fileName: "File 2.png")
    ],
  )
);

Saving multiple files from Uint8List

List<String>? result = await PickOrSave().fileSaver(
  params: FileSaverParams(
    saveFiles: [
      SaveFileInfo(
          fileData: uint8List,
          fileName: "File 1.png"),
      SaveFileInfo(
          fileData: uint8List,
          fileName: "File 2.png")
    ],
  )
);

File Metadata

FileMetadata? result = await PickOrSave().fileMetaData(
  params: FileMetadataParams(filePath: filePath),
);

Picking file and get its metadata

Get cache file path from file Uri or absolute file path

String? result = await PickOrSave().cacheFilePathFromPath(
  params: CacheFilePathFromPathParams(filePath: filePath),
);
