Preheat oven to 325 degrees. Grease and flour a 9-inch bundt pan.
In a small bowl, combine flour, salt and baking soda. In a large mixing bowl, mix sugar and oil for 5 minutes. Add eggs, one at a time. Add vanilla and mix. Add flour mixture and mix just till combined. Fold in walnuts, cranberries, dates or prunes and raisins.
Spoon ½ of the batter into prepared bundt pan. Place ½ the figs around on top of batter and push lightly into the batter. Spoon remaining cake mixture on top of figs. Sprinkle remaining figs evenly on top of cake and lightly press them into cake batter.
Bake for 1 hr 25 minutes or until cake tester comes out clean (I use a long bamboo stick, as a toothpick is not long enough for a thick cake.) Cool in the pan for 15 minutes. Turn out onto a cooling rack.
