AssetManifest.json to no longer be generated in Flutter app builds

[Andrew Kolos]

Hello everyone,

This is an announcement of an upcoming change to how the flutter CLI tool bundles assets into an app.

Currently, the tool generates a file named AssetManifest.json as part of its builds. While AssetManifest.json is an undocumented implementation detail of Flutter, reading this file has been frequently recommended by community members as a way to determine what assets are available in a Flutter app at runtime. Eventually, the tool will no longer generate AssetManifest.json.

If your app or build process is dependent on AssetManifest.json, please see Removal of AssetManifest.json for a migration guide and timeline.
