docs: create a Lingo.dev CLI integration guide for Flutter

[davidturnbull]

Context

We're building a library of integration guides that show developers how to use Lingo.dev CLI with popular frameworks and platforms. Each guide is intended to be a complete, hands-on tutorial that takes someone from zero to having a working multilingual application.

Task

Create a Lingo.dev CLI integration guide for Flutter.

The guide should follow the same general flow, scope, and structure of existing guides.

Example guides

These are some examples of existing guides:

• Godot: https://lingo.dev/en/cli/frameworks/godot
• Mintlify: https://lingo.dev/en/cli/frameworks/mintlify
• Laravel: https://lingo.dev/en/cli/frameworks/laravel
• iOS: https://lingo.dev/en/cli/frameworks/ios
• React Native (Expo): https://lingo.dev/en/cli/frameworks/react-native-expo

Caveat: Merging PRs

Our documentation content lives in an internal repo. This means if you open a pull request for an integration guide, we can't merge it directly. Instead, we use the following workflow to ensure everyone receives credit for their work:

1. Create a pull request for the current repo.
2. In the PR, include a Markdown file that contains the integration guide (e.g., docs/guide.md).
3. We'll review the PR, working with you to get the guide into the best state possible.
4. If we publish the guide on the website, we'll include a byline in the documentation that links to your GitHub profile.
5. Once the documentation has been published, we'll close the PR with a comment that references the document.

Testing

Be sure to test the complete guide by carefully following all of the steps. (This is the most time-consuming part.)

Hi @davidturnbull! I'd like to work on creating the Lingo.dev CLI integration guide for Flutter.

I plan to follow the structure and flow of the existing framework guides (Godot, Mintlify, Laravel, iOS, and React Native). I'll ensure that I thoroughly test all steps locally before submitting the PR, following the workflow outlined above.

I appreciate any feedback or guidance, and would be grateful if this could be assigned to me. Thank you!
