Therefore, the correct approach is to replace all other words with three synonyms, keeping proper nouns intact. For example, in the sentence "The Flutter CLI is a command-line tool," "Flutter CLI" stays, and "is" becomes am etc. However, in the context of the given text, "Flutter CLI" is a proper noun, so the entire term is left as is, and other surrounding words are replaced.
"Scalable" synonyms: "expandable|adaptable|flexible."

Wait, in the text it's "Flutter apps," so "apps" is part of the phrase. Wait, the user said to not touch proper nouns, so "Flutter apps" is a proper noun? Hmm, no, "Flutter" is the proper noun, and "apps" is a common noun. So "apps" can be replaced.
Proceeding further, the next line is "Use unit tests, widget tests, and integration tests to ensure that the app is working as expected." Here, "unit tests," "widget tests," and "integration tests" are terms that might be considered proper nouns or not? "Unit tests" is a common testing type, not a specific name, so they can be replaced. "Flutter" is part of the proper noun "Flutter apps," but in "widget tests," the word "widget" is part of "Flutter widget," which "Scalable" synonyms: "expandable|adaptable|flexible
Next part: "Suppose we’re building a mobile app for a retail company that allows customers to browse and purchase products online." "Building" could be "developing," "creating," or "constructing."

"Online" synonyms: "digital," "virtual," or "web-based."
