Dart SDK Version issue #4

Closed DhavalRKansara closed 4 years ago

DhavalRKansara commented 4 years ago

Hi Shamblett,

While trying to get the packages, I am getting the following error:

Error: Because iot_home depends on grove any which requires SDK version >=2.6.0 <3.0.0, version solving failed.

and the same for the mraa dependency.

shamblett commented 4 years ago

Well spotted, I've updated the SDK constraints, try it now.

DhavalRKansara commented 4 years ago

I think you misunderstood me. My previous comment meant that few of the dependencies( mraa, grove) used in your project had a higher configuration of dart SDK. Currently, the latest stable available version of Dart is 2.5.0, and because of that, I am unable to use your project.

shamblett commented 4 years ago

Latest stable version of Dart is 2.6.1, see here

DhavalRKansara commented 4 years ago

Thanks, Shamblett

it is working fine and I am closing this issue.

DhavalRKansara commented 4 years ago

With Dart SDK version 2.6.1 facing the below issue.

Wrong full snapshot version, expected 'cb187597a166f2c0c64a200e22509ee3' found 'c8562f0ee0ebc38ba217c7955956d1cb'

Isolate creation failed

Did you create the snapshot with dart 2.5.0? I'm not sure what you are trying to do here.

DhavalRKansara commented 4 years ago

The latest stable version of flutter is compatible with dart 2.5.0.

We can upgrade the dart with flutter upgrade command only or is there any other way to upgrade dart SDK?

I tried to download the latest stable release of Flutter SDK(2.6.1) from the link and replace it with the already available dart-sdk inside flutter > bin > cache > dart-sdk but after this steps, I am getting below error:

I'm not a flutter user unfortunately, you may be better asking on a flutter list.

DhavalRKansara commented 4 years ago

@shamblett Which framework did you use?

Would it be possible to change the dart SDK version to 2.1.0 so that this project can be used in a flutter.

shamblett commented 4 years ago

I just use the Dart VM and its SDK, mraa and grove depend on FFI which itself needs Dart 2.6 or above which is where we started, I'm surprised Flutter is so far behind Dart stable, there were a few releases between Dart 2.5.0 and Dart 2.6. Could you not use Flutter dev channel?

bhagujava commented 4 years ago

@shamblett The issue is current flutter stable release support dart<=2.5.0 and one of your Mraa repo contain environment: sdk: ">=2.6.0 <3.0.0"

@shamblett No, I am using the stable channel of the flutter not a dev one.

I already raised a question on StackOverflow for the same issue.

shamblett commented 4 years ago

I'm not sure what you mean, as I said mraa uses the new Dart FFI language feature which is only available in Dart 2.6 or above, it can't use any lower SDK becaus e it won't work, same with the grove package.

DhavalRKansara commented 4 years ago

@shamblett Got it. Thanks for your support.

I will give a try on the flutter dev channel and let's see what happens.
