:DartToggleMethodBodyType. With the cursor on either a return statement
(when it is the only statement in a method block) or on the => in a method
definition, toggle between the two ways to write the method. If it is an
expression body method (=>) convert to a block body ({} and a return) or
vice versa. Recommended mapping (in ftplugin/dart.vim):
noremap <buffer> <leader>tr :DartToggleMethodBodyType<cr>
