Context
I am currently working on a project that requires the use of Dartpad.dev, and I'm looking to modify the Flutter/Dart SDK version for my specific needs.
In a typical environment, altering the SDK version can be achieved by updating the pubspec.yaml file like so:
environment:
sdk: ">=2.11.0 <3.0.0"
However, I'm uncertain how this can be accomplished within Dartpad.dev, given its unique environment.
What I tried:
In an attempt to change the SDK version, I added the following line at the beginning of my dartpad file:
// @dart=2.9
Unfortunately, this resulted in an error message stating:
The language version must be >=2.12.0.
This leads me to wonder if it's even possible to downgrade the SDK version in this environment.
The question
- Is there a way to change the Flutter/Dart SDK version on Dartpad.dev? If so, what is the process?
Side note
I recall that in the pre-null-safety era, when the feature was still experimental, it was possible to alter a query parameter in the Dartpad link to allow for null safety.
However, my requirement goes beyond this, I am interested in changing the actual Dart SDK version, not just enabling or disabling null safety. Is this level of customization possible on Dartpad.dev?
This might work, you can change the channel and run your code.
