In this example, I'm using the built-in search box on the default Windows 10 file browser. Your Visual Studio installation directory is likely C:\Program Files (x86)\Microsoft Visual Studio. Search from those three files in your Visual Studio installation directory and then copy them into your Flutter distribution folder. The libraries from Visual Studio that you need to include in the folder you distribute the executable on are: They will need to unzip the folder and double-click on the binary. Zip the folder and then send it to your tester. The binary needs the other files in the folder to run. Keep the binary in the same folder that Flutter automatically saved it in. There's a quick fix.Īn easy way to distribute your Windows binary for testing is to copy three libraries from Visual Studio into the same folder that the binary is in. If you send your new binary application file to your co-worker, it may not run. You can double-click on the binary and it will launch. The binary will be located in build -> windows -> runner -> Release. Build for DistributionĪfter you finish development or you've at least reached a stage where you want to distribute it to your stakeholders for feedback, you need to build the Flutter app for distribution. This is quite cool and part of the magical feeling of painting the UI with the wonderful Flutter workflow. If you have the Dart and Flutter extensions installed in your VS Code editor, your app can hot reload automatically whenever you save a change. It feels to me like the changes are viewable on the app screen within a second of making a change to the code and saving the change. You can add Flutter widgets into the tree and you do not have to wait for the application to build. It is not built as a native Windows executable until the final build and packaging stage when you are ready to distribute your application. For the development process, the application runs on the Dart VM. You can use hot reload and hot restart during the development process to see your changes quickly. On a 6 core i7 workstation with 32GB of RAM, it took about 20 seconds for the first build. If you have more than one device, you need to specify windows with flutter run -d windows. As I only have one device, I can just use flutter run. Run flutter devices to confirm that you have a windows device.Īt this point, you can access the device similar to an Android or iOS device. On the command line, run flutter -config -enable-windows-desktop to enable Windows desktop support. The specific packages on the right are the default settings when you select Desktop development with C . I'm using Visual Studio Community edition 2019 16.7.6 in this example. You just need to have Visual Studio installed on your development workstation. I use Visual Studio Code for development. You do not need to use Visual Studio for Flutter development editing when you write your Windows desktop applications. When you install Visual Studio, you will see a screen similar to the one below. You only need the Desktop development with C workload. Install Visual Studio, not just Visual Studio Code. Run flutter upgrade after you change the channel to dev. This application sends HTTP requests to the camera to test the camera API.Ĭonfigure Windows and Flutter Environment You can share the executable with your peers and ask them to test your application and provide feedback. The end result is a zipped file that contains a Windows executable. This technique will also work for Linux and MacOS desktops with some modifications for those specific platforms. GitHub code repo and additional information is available from this post in the RICOH THETA Developer Community forum. The 8MB graphic files are a nice test for the Flutter rendering engine on Windows. I'm using a RICOH THETA Z1 camera to test the application which displays and navigates 23MP images. This example shows how to use Flutter to connect a Windows kiosk or laptop to an external camera with WiFi then transfer and display the images. Let's build Windows desktop apps with Flutter and Dart.
