{ "language": { "blogs details": "blogs details", "Search products": "Search products", "Somethings went wrong": "Somethings went wrong", "Become seller": "Become seller", "Cart": "Cart", "Your name": "Your Name", "Checkout": "Checkout" } }

I'm Expecting like this

{ "language": { "blogs_details": "blogs details", "search_products": "Search products", "Somethings_went_wrong": "Somethings went wrong", "become_seller": "Become seller", "cart": "Cart", "your_name": "Your Name", "checkout": "Checkout" } }

Map newMap = {};
data.forEach((key, value) {
