How to upgrade the Flutter project
Flutter SDK 2.0 to 3.0
I'm leading or guiding a flutter team(2-3 people) at ketto.org where I've to make apps in solid form which matches the industry app standards. I've more than 5 years of experience [2+yr remote] in mobile platforms
with service and product- based companies. I'm very
passionate to write code for thousands of users.
I'm sharing my experience when I upgraded my existing application to the latest Flutter SDK version.
This is a practice that I suggest to every Flutter developer who wants to upgrade his existing application to the latest version of Flutter SDK.
(Optional) -> Create a new instance/user account to your existing Mac/windows system to not affect your current project settings and configuration. Because we can't take risk for existing project. I do the same on my MacBook, creating a new user login and configuring everything.
Now open a terminal and come to your project path. (c/path/to/your/project)
run 'flutter upgrade'
Update project dart version
sdk: '>=3.1.0 <4.0.0'Run 'flutter pub get'
Now let's update all the dependencies via the following command
flutter pub outdated'flutter pub outdated' -> This command can help us to see all the possible versions.
Now once we have checked and reviewed run the below commands
flutter pub upgrade --major-versions flutter clean flutter pub getWe can use 'dart fix' and 'dart migrate' while updating the dart version and error fix. Note 'dart analyse' also helps.
