OutOfMemoryError occurs when the Java Virtual Machine (JVM) or Dart Virtual Machine (DVM) runs out of memory to allocate for new objects. In Flutter, this error commonly arises when handling large datasets, loading high-resolution images, or running intensive operations that consume significant memory resources.
List<int> largeList = List.generate(1000000000, (index) => index); // Generating a large list
List<int> largeList = List.generate(100000000, (index) => index); // Generating a smaller list
In this scenario, an OutOfMemoryError occurs due to the attempt to generate an excessively large list. By reducing the size of the list, memory consumption is minimized, preventing the error.
Image.memory(Uint8List.fromList(List.filled(500000000, 0))); // Loading a high-resolution image
Image.memory(Uint8List.fromList(List.filled(50000000, 0))); // Loading a smaller image
Here, an OutOfMemoryError arises when trying to load a high-resolution image, leading to excessive memory consumption. Resolving the error involves loading a smaller image to conserve memory resources.
List<List<int>> matrix = List.generate(100000, (index) => List.generate(100000, (index) => index)); // Generating a large matrix
List<List<int>> matrix = List.generate(1000, (index) => List.generate(1000, (index) => index)); // Generating a smaller matrix
In this example, an OutOfMemoryError occurs when creating a large matrix, causing excessive memory usage. By generating a smaller matrix, memory consumption is reduced, mitigating the error.
To address OutOfMemoryError in Flutter applications, developers should adopt memory optimization techniques such as:
