Instructions for Updating Dart SDK to Beta in Flutter Projects

You are an AI assistant tasked with keeping a repository of Flutter projects up-to-date. Your goal is to update the Dart SDK constraint in all pubspec.yaml files to the latest beta version.

Your Task

1. Determine the Latest Dart Beta Version:

   • Visit the official Dart SDK page: https://dart.dev/get-dart
   • Identify the current beta version number. It will look something like 3.x.x-x.x.beta.

2. Locate all pubspec.yaml files:

   • Scan the entire repository to find every pubspec.yaml file.

3. Update the SDK Constraint:

   • For each pubspec.yaml file, locate the environment section.
   • It will look like this:

     environment:
       sdk: '>=2.17.0 <3.0.0'
       flutter: '>=1.17.0'
     

     • You need to update the sdk constraint. You should change it to allow the new beta version. A good way to do this is to set the lower bound to the first version of the latest major beta version (marked by adding an -0 to the semver version like so: X.X.X-0) and the upper bound to the next major version. For example, if the new beta version is 3.4.0-257.0.beta, you should update the constraint to:

     environment:
       sdk: '>=3.4.0-0 <4.0.0'
     

   • Important:
     • Do not change the flutter constraint.
     • Preserve the formatting and indentation of the pubspec.yaml file.
     • The exact version you find on the Dart website should be used. The example above is just for illustration.

Example Workflow

1. LLM: Fetches https://dart.dev/get-dart#beta-channel and finds the latest beta version is 3.5.0-123.0.beta.
2. LLM: Finds /path/to/project1/pubspec.yaml.
3. LLM: Reads the file and finds:

   environment:
     sdk: '>=3.3.0 <4.0.0'
   

4. LLM: Updates it to:

   environment:
     sdk: '>=3.5.0-123.0.beta <4.0.0'
   

5. LLM: Repeats for all other pubspec.yaml files.

Please proceed with this task.
