Examples

Pick an image file

  final params = OpenFileDialogParams(
    dialogType: OpenFileDialogType.image,
    sourceType: SourceType.photoLibrary,
  );
  final filePath = await FlutterFileDialog.pickFile(params: params);
  print(filePath);

Pick a document

  final params = OpenFileDialogParams(
    dialogType: OpenFileDialogType,
    sourceType: SourceType.photoLibrary,
  );
  final filePath = await FlutterFileDialog.pickFile(params: params);
  print(filePath);

Save a file

final params = SaveFileDialogParams(sourceFilePath: "path_of_file_to_save");
final filePath = await FlutterFileDialog.saveFile(params: params);
print(filePath);

Pick a directory and save a file to the picked directory

if (!await FlutterFileDialog.isPickDirectorySupported()) {
  print("Picking directory not supported");
  return;
}

final pickedDirectory = await FlutterFileDialog.pickDirectory();

if (pickedDirectory != null) {
  final filePath = await FlutterFileDialog.saveFileToDirectory(
    directory: pickedDirectory!,
    data: file.readAsBytesSync(),
    mimeType: "image/jpeg",
    fileName: "fileName.jpeg",
    replace: true,
  );
}

Optimize picked image file using flutter_image_utilities

Use the plugin flutter_image_utilities to optimize a picked image file.

  final params = OpenFileDialogParams(
    dialogType: OpenFileDialogType.image,
    sourceType: SourceType.photoLibrary,
  );
  final filePath = await FlutterFileDialog.pickFile(params: params);
  print(filePath);

  if (filePath != null) {
    final pickedFile = File(filePath)

    // optimize the image file
    final optimizedFile = await FlutterImageUtilities.saveAsJpeg(
      sourceFile: pickedFile,
      quality: 60,
      maxWidth: 1920,
      maxHeight: 1024,
    );
  }
