Migrate Flutter Code

Use for framework/API/state-management migrations.

Workflow

1. •Define migration target and acceptance criteria.
2. •Run baseline analysis and tests.
3. •Apply migration in small batches by module.
4. •Re-run analysis/tests after each batch.
5. •Address deprecations and remove temporary adapters.
6. •Final pass for style, naming, and docs.

Guardrails

• •Do not mix unrelated refactors with migration work.
• •Keep intermediate states buildable when possible.
• •Prefer codemod-like repetitive edits over ad hoc changes.
• •Attach validation status to each migration batch.

Required output

1. •Migration target and acceptance criteria.
2. •Batch-by-batch changes summary.
3. •Validation commands/results per batch.
4. •Breaking changes and rollback notes.
