Why this matters: If you navigate back to a page with a Scrollable that has a nonzero scrollOffset, we will restore that scrollOffset. We clamp the scrollOffset to the contentExtent before the first layout, before contentExtent is updated to its proper value. Initializing contentExtent to INFINITY effectively disables the first clamp, until we can get a valid value from layout. Since the previous scrollOffset was valid, it seems safe to assume it's still valid. BUG=https://github.com/flutter/flutter/issues/4883 BUG=https://github.com/flutter/flutter/issues/4797
Flutter
Flutter is a new way to build high-performance, cross-platform mobile apps. Flutter is optimized for today's, and tomorrow's, mobile devices. We are focused on low-latency input and high frame rates on Android and iOS.
Flutter is an early-stage open-source project. We are still missing core features like accessibility, text input, localization, and more. However, you can build demos and examples today. We hope you try it out and send us feedback.
