This week in Flutter #29

About web, community, and code samples — Q3 2021 survey results

The results from the latest quarterly Flutter survey are out. They mainly asked for opinions over Flutter for web. 38% of developers worked on a web app using Flutter in the month prior to the survey. That is way more than I expected.

And I do agree that "initial page load" is one of the worst experiences in Flutter web apps.

I am also surprised to see that 36% of developers think that SEO capabilities should be improved, completely missing that a Flutter web app should not be used as a marketing website 😑.

🔗 Read shared preferences from native apps

I have been thinking about the problem described in this article in the past. If you migrate your app from native to Flutter, you do want to keep the current state when a user downloads the update that migrates to Flutter. You do not want users to be logged out, or data saved in shared preferences to be lost. Marc Gerken describes how you can access the data saved in shared preferences by the native version of your app, from the Flutter version.
