uninstall.sh

#!/usr/bin/env bash
#
# flutter-cli uninstaller — reverses `install.sh`:
#   1. Strips the `# >>> flutter-cli shim >>>` block from every supported
#      rc file we find (idempotent — skips files where the block isn't
#      present, so it's safe to run twice).
#   2. Removes the `flutter-cli` binary from every known install
#      location (~/.local/bin, ~/.cargo/bin, /usr/local/bin, $BIN_DIR)
#      plus `cargo uninstall flutter-cli` (and the legacy `fl-cli`) for
#      build-from-source installs.
#
# Usage:
#   ./uninstall.sh              # remove shim + binary
#   ./uninstall.sh --keep-bin   # remove the shim only, leave the binary
#   ./uninstall.sh --keep-rc    # remove the binary only, leave rc alone
#   BIN_DIR=~/.local/bin ./uninstall.sh   # also check this extra dir
