What is Flutter?
Flutter is an open source framework created by Google known for its ability to build beautiful, fast, and productive applications. It compiles code to ARM or Intel machine code, ensuring a high-performance experience across mobile, web, desktop, and embedded platforms. Flutter's flexibility and speed, along with its global community of developers, make it a popular choice for Google and many other brands.
Flutter is not just a tool for application development; it is a comprehensive ecosystem, powered by the Dart programming language, also developed by Google. This framework is designed to be productive and flexible, allowing developers to create a wide array of applications with a single codebase. The trust it has earned from various brands solidifies its reputation as a reliable framework for modern software development.
Exporting Flutter Data to a CSV File
Using the csv and path_provider Packages
To export a list to a CSV file in Flutter, you can utilize the 'csv' package in combination with the 'path_provider' package. First, request permission to write to the device's storage using the 'permission_handler' package. Then, with the 'path_provider' package, use the getExternalStorageDirectory() method to retrieve the path to the device's Downloads directory. Convert your list to a CSV string using the ListToCsvConverter() code snippet provided by the 'csv' package. Finally, use the exportCSV.myCSV method, providing the desired header and your list of lists as arguments, to create and export the CSV file.
Using the to_csv Package
The 'to_csv' package, which is compatible with Dart 3 and Flutter, allows for the creation of a CSV/Excel file from data within a Flutter application. After adding 'to_csv' as a dependency in your pubspec.yaml file and importing it into your Flutter project, use the exportCSV.myCSV(header, listOfLists) method to generate and download the CSV/Excel file. This method requires two arguments: a header list and the 'listOfLists', where each inner list contains fields for one row of the CSV file.
Alternate Packages for CSV and Excel Export
Other packages such as 'syncfusion_flutter_xlsio' can be used to create an Excel file, while the 'open_file' package can open a file after creation. It's important to note that the 'ext_storage' package, previously used to get the downloads directory, has been deprecated and replaced by 'path_provider'.
