Maps can be transformed using methods like map, where, and addAll. main.dart void main() { var original = {'a': 1, 'b': 2, 'c': 3}; // Transform values var squared = original.map((key, value) => MapEntry(key, v
* For those maps, a lookup using this operator cannot distinguish between a * key not being in the map and the key having a `null` value. * Methods like [containsKey] or [putIfAbsent] can be used if the distinction * is important. */ ...

A for loop can be used for traversal of containers such as lists or maps. From the length property of the list we get its size. main.dart void main() { final planets = [ "Mercury", "Venus", "Earth", "Mars", "Jupiter", "Saturn", "Uranus", "Pluto" ]; for (int i = 0; i...
Tests if geometry1 contains geometry2. convexHull(Geometry geometry) → Geometry Calculates the minimum bounding geometry (convex hull) that completely encloses the given geometry. convexHullCollection({required List<Geometry> geometries, required bool merge}) → List<Geometry> Calculates the minimum ...
The only difference is that the catch block (instead of the ON block) here contains the code to handle the exception. The parameter of catch contains the exception object thrown at runtime.Open Compiler main() { int x = 12; int y = 0; int res; try { res = x ~/ y; } catch(e...
Over the last couple of years, it has become the leading choice for developers who want to build apps for multiple platforms; but designers need a visual tool for prototyping and creating Flutter UI, rather than handcrafting Dart source code. Enter XD to Flutter! It’s been almost a year ...

The most enriched motif from in vitro DART-Seq assays using APOBEC1-YTH contains a GGACU sequence, which matches the m6A consensus (top; n = 9,428). In contrast, the top motif from in vitro DART-Seq assays using APOBEC1 alone fails to show enrichment for an m6A consensus motif (...
