Need to download a file and open it in Flutter?🌐

No problem, with this flutter package it is done in a few lines.

Getting started 🚀

Just simply add the download_file package to your dependencies:

dependencies:
  download_file: <Newest version>

Download a file ⬇️

DownloadFile.downloadAndSafeFile(
              downloadFileOptions: DownloadFileOptions(
                downloadUrl: 'https://jsonplaceholder.typicode.com/todos/1',
                fileName: 'todo.json',
              ),
              context: context,
            );

To download a file just use the DownlaodFile.downloadAndSafeFile() method. Here you need to pass the current context and a DownloadFileOptions with a downloadUrl ('https://jsonplaceholder.typicode.com/todos/1') and a fileName ('todo.json') how the file should be saved as.

DownloadFileOptions 💾

While you can pass a downloadUrl and a fileName as described above, you can additionally add a customSavePath. This can for example be "users/images". This will save the file into the "users/images/[fileName]" directory.

DownloadFileOptions(
                downloadUrl: 'https://jsonplaceholder.typicode.com/todos/1',
                fileName: 'todo.json',
                customSavePath: 'user/todos'
              ),

Custom widgets 🚧

To modify the appearance of the widget, you can pass the following parameters:

DownloadFile.downloadAndSafeFile(
              downloadFileOptions: DownloadFileOptions(
                downloadUrl: 'https://jsonplaceholder.typicode.com/todos/1',
                fileName: 'todo.json',
                customSavePath: 'users/todos'
              ),
              context: context,
              errorMessage: 'This is an example error message...',
              loadingWidget: CustomLoadingWidget()
            );

Setup method (optional) ⚒️

You can also modify the default values of the package, so you don't have to pass them manually everytime. Just use the DownloadFile.setup() method in your main method for that.

void main() {
  DownloadFile.setup(
    defaultErrorMessage: 'This is an example error message...',
    defaultLoadingWidget: CustomLoadingWidget(),
  );

  runApp(const MyApp());
}
