Eric Windmill 2999d738b8 Dart 3.9 / Flutter 3.35 [first LLM release] (#2714)
I got carried away with Gemini and basically rewrote CI and the release
process for the new LLM reality. This work was largely completed by
Gemini.

- Bump all SDK versions to the current beta (3.9.0-0)
- Run `flutter channel beta`
- Wrote `ci_script.dart` to replace the bash scripts
- Converted repository to pub workspace #2499 
- Added llm.md and release.md
- Added redirect for deprecated Samples Index

Platform Channel Samples

A sample app which demonstrates how to use MethodChannel, EventChannel, BasicMessageChannel and MessageCodec in Flutter.

Goals

  • Demonstrate how to use MethodChannel to invoke platform methods.
  • Demonstrate how to use EventChannel to listen continuous value changes from the platform.
  • Demonstrate how to use BasicMessageChannel and MessageCodec to send messages of different types across the platform.

The important bits

Method Channel demo

Demonstrates how to implement a MethodChannel to increment and decrement a counter.

Event Channel demo

Demonstrates how to implement an EventChannel to listen to value changes from the Accelerometer sensor from native side.

Platform Image demo

Demonstrates how to implement a BasicMessageChannel using StandardMessageCodec to load an image from native asset.

Basic Message Channel demo

Demonstrates how to implement BasicMessageChannel using JSONMessageCodec, BinaryCodec and StringCodec to send and receive data about pets.
