Stir flour into the skillet with the sautéed onions, cooking briefly until combined. Pour the prepared pineapple juice mixture into the skillet and bring to a boil. Boil 10–15 minutes, stirring often, until the sauce thickens.

Arrange chicken breasts in the base of a slow cooker. Pour thickened sauce over the chicken, ensuring even coverage. Cook on low heat for 8 hours.

Remove chicken from the slow cooker and shred using two forks directly in the pot. Mix to evenly distribute the sauce. Serve hot on sandwich rolls, over rice, or atop salad as desired. If the sauce is thinner than preferred, prop open the slow cooker lid and allow additional liquid to evaporate before shredding.
